Repair or Sell? Seeking advice

Hello all, longtime reader, first-time poster.

I have a 2011 Prius with 156k miles facing some potentially heavy repairs. I've listed them all, with complete service history below. For those of you who've seen a lot of these, I'm seeking advice whether to repair or invest in a newer prius / older Toyota (I don't have much $ to spare right now).

I can probably do brakes and suspension myself, but I'm not sure whether it's worth stacking a bunch more miles on this car or if I'm just going to keep having problems. I know 2011 isn't the best year.

Thanks so much for your advice!

Upcoming Repairs:
Brake Booster / Actuator (seems to be gradually failing since 150k, but unsure)
Front Suspension (totally shot)
Full Brake replacement
EGR valve seems to needs cleaning
Hybrid Battery getting lower..
Also need new tires...
