Most of my apps come from F-Droid/IzzyOnDroid repos. Only non-FOSS apps I have are Steam, Stremio/Nuvio, and PodcastGuru. Bonus: Warden scan report that lists all trackers/loggers contained in these apps.
That's a great list.
I just want to call out that Breakout 71 is a fun, light game I play too, when I need to kill a couple of minutes without thinking too hard.
