I had the same issue w being unable to eliminate them entirely for ages. Putting a layer of sand over soil in pot was what finally completely resolved it for me (in addition to continuing all the other stuff you mentioned).

I’ll give it a shot! How thick of a layer? Like a cm or 2?

I also had success with sand on top, a couple cm is fine- just enough to completely cover all visible topsoil. You may also want to start bottom watering if you can and leave the top undisturbed since the sand will migrate when you top water. You may need to reapply sand periodically so get a decent sized bag
