Depends on your own use case but I’ve been using BlissOS (https://blissos.org/) on an old HP Elite X2. As Bliss is essentially just Android-x86, it’s fairly polished; only thing that I haven’t figured out is configuring the hardware volume buttons.

Have yet to add an Acebeam to my collection, this looks like a good one for sure!

Convoy L7 definitely has the form factor but no Anduril.
