I'd love to have managed 2.5Gb switches with 10Gb uplinks in my house using a custom linux OS that I can use standard config management tools with...
100%, this has been the most frustrating thing about following the various "open" switching worlds. There's a massive gap in the middle between the sorts of 4-8 port switches that end up in OpenWRT-compatible routers and this sort of enterprise switch that's barely accessible to the "homelab" class user.
I would absolutely love to have some open switching in the "Ubiquiti" class, desktop and 1U rackmount devices with gigabit through 10G as their primary interfaces. I'm personally in the VoIP world and if I could install Asterisk directly on a 48 port PoE switch I'd be deploying them by the dozens.
Me too. I have been eyeballing "SparX-5" based switches, which do run Linux ("SMBStaX"), but you'd need something like million bucks to get anywhere :( Could be candidate for a Kickstarter style project maybe...

Sadly my PCB design skills are not quite up to dense BGA escape + 25gig lanes...
Check out DENT NOS: https://dent.dev/ There's a Delta 32x1G (PoE+) + 16x2.5G (PoE++) + 6x25G SFP28 switch that can run DENT.
