OK, so my final thoughts -- maybe some of this you already know...
Your internal 1 TB flash drive is already really really fast -- i think it benchmarks at near 2500 MB/s. So if its already slow with the photos database... moving to an external SSD (500 MB/s) or even NVMe flash (1500 MB/s) drive may not help?
the 4 TB platter is perfect for hours TM backups... but you could *easily* also use it for the monthly bootable clone. Either as is, or dedicate a 1 TB partition to it. Sure, the first clone might take a while, but incremental bootable clones later should take a fraction of that. Using a SSD here seems overkill.
You dont/shouldnt need the speed of an SSD for a backup?
The NVME I guess would make the most sense for an external photos only drive, since its the fastest.
You could easily have this structured as
A) internal drive
B) NVME
Both backup to
C) platter with TM (for both internal and NVME) and part for bootable (internal only)
If you think C is too small, then id spend my $ on a bigger platter.
3 drive instead of 4, and 2 boot drive backups + backup of photos drive.
