Whatever you do, don't spend a minute on any piece that you have no feeling for. Life is too short! Leave them to the pianists that love and understand them.
I guess a lot depends on what you actually do as a musician, but I think that for many people the reality is that sometimes they /have/ to play things which they don't personally like. So it's important to be able to knuckle down and put the work in even if you don't care for the work in question. For the same reason, it's good to make sure you can play different styles of music, not just the one(s) you like best.
Of course it's nice to be able to focus on stuff you actually like and I'll cheerfully admit to doing way more practice on pieces that I enjoy than on stuff I don't. But I try to exercise a bit of self-discipline and plough through the other stuff too.
Sometimes I work away at a piece I'm completely indifferent to, but as I get to grips with it I start to like it better and eventually it grows on me and I end up really enjoying it. If I didn't start off by spending several hours on it, I'd never have discovered any feeling for it.
If you just want to play for yourself, you can play whatever you like. But if you want to play in ensembles, act as an accompanist, play for services, etc. you need to be able to play whatever is asked of you.

Rather than ask for suggestions of what to learn next, you should listen to more piano music. Be adventurous. Listen to works by composers and pianists you have never heard of, or who you did not think of as piano composers. Before long you will have a huge list of pieces that you would like to be able to play. A side benefit of doing things this way is that you end up with an unusual and interesting repertoire, so people are more interested in hearing you play. Your teacher should be able to suggest which pieces on your list would be reasonable to attempt at your present level of development. But is is surprising how much progress you can make with a piece that looks to be way beyond your present skill level when you really, really, want to be able to play it.
I half agree with you on this, but I think it depends in part on how much you care about the instrument. I don't enjoy listening to piano music at all. There was a piano recital at music summer school and I bunked off (it wasn't compulsory) to go look at a local cathedral organ and visit an organ builder's workshop. I'm never going to be a pianist, it's not my instrument of choice and I don't really connect with it. But I recognise that being able to play the piano to some extent is a useful skill for any musician, so I'm trying to make a bit of progress with it. I have very little idea about what pieces would be good to look at next, so, like several others on the forum, I'm open to suggestions and advice from people who have far more knowledge of what's out there.
Your way works better for people who care about the piano (or for whatever instrument it is that people do care about). It works for me on other instruments - I go to lots of organ recitals, I listen to the voluntaries at church, I page-turn for organists whenever I get the chance to, etc., so I'm getting regular exposure to organ music and I have an ever-growing list of "stuff I want to play one day" (some of which I've dabbled with a bit even though it's way way beyond my current ability). But even with organ, I ask for recommendations for repertoire to look at. I don't want to miss out on some great stuff just because I didn't know it existed.
Playing stuff that's way above your present level can mean you just end up butchering it and/or developing bad habits, which make it harder to learn to play it properly even when your playing standard has improved enough. One of my FRCO friends said that he finds it hard to take an easy piece that he learned in his early stages and play it well now because the flaws he brought to it at the time are deeply ingrained - it's a lot easier for him to take a much harder piece and learn it from scratch. So even pieces of the 'right' standard can suffer from being learned when you're still inexperienced.
I do tackle some stuff that's way too difficult, but I also listen to my teachers when they tell me that I should wait a while before I try a particular piece. It works the other way round too - sometimes my teachers will suggest things that I'd never have picked for myself. One of them's just set me something in F minor and I'm already missing out flats all over the place. I don't like it at all right now, but I'm sure it will grow on me (it's Bach - I'll probably love it to bits by the time I've pencilled in half the flats!). She also got me to start on a jolly piece by Lang which I took an instant liking to, but hadn't though to try for myself as my usual organ doesn't have a Tuba stop (which it requires). So there's still a place for recommendations, even when you find plenty of new stuff for yourself (which I do - I turned up to my lesson armed with something I'd heard at a recital, got stuck in my head, located in my Bach book and started to tinker with).
Similar things happen with piano music for me - someone points me at something I wouldn't have chosen for myself and I end up enjoying it.
So, I agree that finding stuff for yourself by listening and exploring is good, but it's not the only way to go and it doesn't work if you don't like an instrument enough to listen to its music.

The piano repertoire is so vast that you could spend your whole life learning only pieces that you absolutely love to bits, and still barely scratch it.
I couldn't! if I only played music that I love to bits, I'd never play any piano music at all. ;-)
I think that piano is an instrument that quite a few people play because it's useful rather than because they love it. It's a very common second study instrument.
So, for some of us, being driven by what repertoire we love isn't going to do much (if anything) to help us develop our piano playing.
