Komorebi is quite good, although it has it quirks with some applications that spawn child processes.
Make sure to make yourself familiar with application specific configs, there's already a whole community-driven config for that [1]. But all in all it's very beginner friendly, since it does enable you to float windows still (and pause komorebi).
