I have an ancient Pixel 3 that still works. I’d like to install a new, third-party OS. Which would you recommend?

I can see that there are many: Lineage, Calyx, /e/, Graphene, … How do I make the decision? Can all of them work on a phone as old as my Pixel 3?

Edit: holy shit, I just installed Lineage OS on my lunch break! I’ve installed “alternative” OSes before on computers but never on a phone. I just followed the instructions (which were a little confusing as there were nested steps) and it’s up and running!
