That's my new router board, if it works okay!
And... if i can buy it anywhere...
I have an ordinary Orange Pi 5 for my HomeAssistant setup and it's quite alright. Having a real NVME SSD in there instead of an SD card gives me peace of mind. I did some tests with zstd and found it about 50% the speed of my Threadripper (restricted to 8 cores for the test). The non-efficiency cores are therefore probably more than twice as fast as a 2 generation old AMD chip, which is pretty impressive.
For the cost of the Orange Pi 5 Plus, you're starting to get into similarly-equipped Intel N100-based machines. I haven't seen any benchmarks comparing the two, but I'd assume it's faster. So you might want to look at those. (Amazon is expensive; everyone gets these from AliExpress. I also don't know how well modern Intel machines do booting without a keyboard and a mouse; the ARM SBCs do great.)
As for Intel machines, most i've found lately seem to be oriented towards home theater, a lot of useless (to me) video outputs and never enough network cards.
Not sure how low power they are either. This is the Intel that seems to have stopped caring about power consumption completely to win the speed race, and people are buying so why would thy care?
Right now I'm still using a dual core Atom Dsomething from I don't remember when, its main quality is it eats 15 W including 2 spinny discs (2.5" 5400 rpm). An Orange Pi with a ssd and the GPU turned off might eat even less.
