There are lots of good FOSS options.
I would strongly recommend checking this site for the trackers in an app if you’re at all concerned about privacy. Links to each app’s exodus privacy report is also at the end of the table linked above.
FYI, Nova has been owned by a data mining company for many years and it is worth moving away from even if you think it is good enough now and doesn’t need updates.
The Exodus Report is really good, I would also recommend https://f-droid.org/packages/io.github.muntashirakon.AppManager/ . you can install an app, then check it with App Manager, before first run, which will often find more trackers than Exodus will
Edit: and https://themarkup.org/blacklight for finding trackers in websites
