Thats more than enough. I can't blame you for being frustrated, if I had those issues I would be right there with you.
I don't have AirPods Pro so I can't speak for their quality at all. My Gen 1 AirPods got really flakey before I got new Gen 2 AirPods (not Pros). I since have retried them after 'forgetting the device' and resetting them and now they actually seem to work better (minus the dying batteries from years of us). I have the rest of those devices and non have given me any of those problems (aside the normal trivial stuff).
For example normal stuff being devices I have that can hibernate wakes on a dead IP on occasion. Considering my MBP is the most used device, I experience the issue the most with my Win10 ThinkPad.
HomePod, Unlock with Watch and Mail have all worked fine for me. One time the stereo pair stopped working with the HomePod, power cycle fixed it though.
AirDrop puts photos in the order they were captured (encoded). Confusing without looking at the metadata since the created and modified dates will be new but (again, for me) its in the proper order. I normally view photos through 'Recents' though because for me that makes it more logical.
It seems like a lot of your problems revolve around network issues. I know its a pain but have you tried resetting network settings? HomePod transfer and device detection, Unlock with Watch, AirPod connectivity, Mac Wifi, syncing all use bluetooth and/or Wifi. Something is very not right there and I know these devices are capable of functioning correctly, or at least as well as mine do.
