Maybe Fokus launcher ? https://f-droid.org/packages/io.github.luantak.fokuslauncher/

I don't think there is really. I haven't even encountered many good Foss launchers except Lawnchair.

Fair phone launcher is on f-droid iirc.

Can't speak for it being open source or not buy it was a good simple launcher worth checking out.

PLEASE READ: GUYS im talking about the TECH company nothing, not something minimalist!! no worries if you've already commented something thats not what im looking for, but ill just probably ignore it

I use Olauncher https://f-droid.org/packages/app.olauncher/

The best I could find is what appears to be AI slop, sorry.

I don't think anything else exists that does all you're looking for. You might be able to get somewhat there with something like lawnchair and some icon packs though

It's a fork of a launcher I used before, because it stopped getting updates. I think there are multiple such forks, which is why so many look and feel similar.
