1.PCi-E 5 - not important at moment but may be one day
PCI-E 5.0 SSD you can get even on some of the more affordable boards like the TUF B650-Plus. PCI-E 5.0 graphics, I'd look at the B650E-F Strix, there's a fair few owners of this board on the forum.
2. 3 x m2 - Sata ok if included but I do not use at moment
So long as you avoid the cheapest/lowest-end B650 boards, 3x M.2 is fairly common.
4. I use both 1gb and 2.5 gb lan and find that they both work well . WiFi I do not use at the moment as am cabled BUT useful to have
This is a problem, 2x LAN is very rare nowadays.
I only know of two boards with 2x LAN:
X670E Steel Legend (2.5Gb & 1Gb)
B650 Creator (2.5Gb & 1Gb)
3. I use a soundblaster z sound card hooked to a logitech 5.1 speaker system so that at the moment I have no use for SPDIF
The B650 Creator has a baby PCI-E 1x slot that is a decent distance from the primary PCI-E, so I think you could use that. The 3rd PCI-E full length slot shares bandwidth with the 3rd M.2 slot, so that would be unsuitable.
X670E Steel Legend has a baby PCI-E 1x slot, but it looks closer to the primary PCI-E than the Creator (might just be my eyes), but you can use the bottom full-length slot on this board, with (so far as I can see, I haven't studied the manual) no impact on any M.2 slots.
I have enjoyed my 570 board excepting that it only has 2 x m2 slots so the newer B650 solves that problem
