Unsure if people are still looking for launcher recommendations, but some free/libre & open-source options which have received at least one update in 2023 are (with the caveats this list is not exhaustive and its categories rough) the ultraminimalist (text list-only, reminiscent of old Niagara) OLauncher and its slightly more feature-rich fork mLauncher, the minimalist (text-based but more developed ui) Focus Launcher and the feed-based Lunar Launcher, the mediumist (slightly more feature rich than minimalists or Graphene Launcher, still focused on 'clean' home screen over customizability) Discreet Launcher and slightly more developed Tiny-Bit Launcher, the maximalist (intended to be feature-rich foss alternatives of popular proprietary launchers with rough parity in customizability) previously mentioned Lawnchair originally based on the Pixel Launcher which is behind on updates but supposedly getting their shit together and Neo-Launcher originally based on Nova Launcher, and finally the search & scroll (searchbar-based with option for infinite scrolling widgets as well) minimalist KISS & feature-rich Kvaesito.
I personally bounce between Kvaesito & Neo-Launcher once or twice a year, and really like KISS as well, and feel all three are quality projects. I know of some other neat options which are unfortunately no longer maintained, but am happy to share those as well.
