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.)
