Only difference really between Intel vs AMD for self hosting is ECC compatibility. Personally, I tend to be picky about ECC for my server builds (all done on ATX systems thus far), so I go for AMD, but for smaller use case scenarios outside of ZFS pools it shouldn’t matter a ton. If you go the AMD ECC route you’ll have to set aside a spare GPU for local bios/terminal use (or go for the 4000 series pro version of Ryzen, can be had on ebay from resellers for decent prices). otherwise Intel and AMD don’t differ function wise outside of ECC concerns, just make sure to match it with a chipset that will give you the lanes you need to allow for future expandability pcie-wise. (the expandability wasn’t a concern when I first started, but as my self hosting needs expanded I had to replace a motherboard). can’t comment much to wifi APs (I run pfsense and wall off my wifi on it’s own vlan, I ran ethernet throughout the home and my wifi devices that need access to my main network tunnel through via wireguard)

been running it in docker for over a year now with the docker hub image. I’m assuming you got to the app site page based off of what you described. I’d imagine it may be something related to the video quality/encoding option? Does the metadata come through when you search for a video? Also, I find Invidious tends to be (rightly so) particular with the TLS stapling option, so if you don’t have tls or a proxy in front of it, then make sure it’s set to off (happened to me with self signed certs and nothing would play)
