sfp+ is clearly cheaper, and less heat/power, but I've got cat5e in the walls and between my house and detached garage, so I've got to use 10g-baseT to get between the garage and the house, and up to my office from the basement. At my two network closet areas, I use sfp+ for servers.

I think my muni fiber install happening this week might have a 10G-baseT handoff, and I've got a port for that open on my switch in the garage. If that works out, that will be neat, but I'll need to upgrade some more stuff to make full use of that.

Oh true, good point, being wired for ethernet is another valid usecase. I'm lucky in that my ONT is just a commodity Nokia switch I can slap any sfp+ form factor transceiver I want in the appropriate port of for the connection to the router, so in my case 10gbe is truly banishable to the devices I can't get a pcie card into. I'm still in the phase of masking taping cables to the ceiling instead of doing real wall pulls, but when I do get around to that I feel like I'm going to pick up an aliexpress fiber splicer and pull single-mode fiber to futureproof it and make sure I never have to deal with pulls again (and not be stuck on an old ethernet standard in the magical future where I can get a 100gbit wan link).
