SD cards hop on the PCIe 4.0 bus to hit 4GB/s with version 8.0 of storage spec:
As outlined in a whitepaper [PDF] this month, the new spec will let existing SD Express and microSD Express cards employ PCIe 4.0 and NVMe to deliver a top speed data transfer speed of [3938 MB/s].
While the new spec is backwards-compatible, the latest top speed will only come with a card reader capable of connecting to the extra row of pins present on SD Express cards that support dual PCIe lanes.
[...] The good news is that SD Express and microSD Express cards can still get to 1970 MB/s on a device with a single PCIe 4.x lane under version 8 of the specification, and SD Express can get there with a pair of 3.x lanes. Which is rather faster than many SSDs and, as SD Express can climb to 128TB on a single card, a rather tasty storage option.

H.265 tiers [wikipedia.org] include up to full 8K (8,192×4,320) @ 120 Hz.
H.266 [wikipedia.org] will have support for 16K, 360-degree videos (not sure what that entails), and 48-bit deep color (16 bpc):
On top of everything you mentioned, there is High Dynamic Range, which may or may not eat into that color depth. I think it depends on the standard.
AV1 looks similar to H.265. Nobody knows what AV2 will add yet, but it will probably be more of the same.
