If I’m being honest, an airline career simply wouldn’t be worth commuting to. But that is just me and obviously tens of thousands of pilots make it work, many very happily. I also happen to live in a domicile that I’d live in even without this job, so that’s easy for me to say.

Any Internet advice from anonymous people who don’t know your situation (personality, family situation, likes/dislikes, finances, hobbies, etc.) is honestly pretty worthless. Even advice from one’s closest friends and family can tend to be advice those friends and family are really just giving themselves. But since you’re here asking…if I were living in LA and junior on the 320, I would stay put and let my seniority rise incrementally for the next couple of years. I’d avoid Virginia Ave and keep my powder dry (and seat unlocked) to get a sense of where this company and this industry and this country and NB big packs are headed. The ER category is nothing like it was even 10 years ago - the airplane wouldn’t draw me, and I wouldn’t find the seniority penalty to switch to it (I think you’ll rise faster on 320) worthwhile. Good luck to you - in the end there’s more than one right answer and you can enjoy any path you end up on.
