They used to have replacements for E-T-A 10A circuit breaker 2210-S111-N1T2-H0 but it looks like those are no longer available.
So far I have not been able to find a drop in replacement for the groups of four breakers used on the panel so it appears I may be looking at having to replace the entire panel.

Blanking plug part number: 33-482-01
It appears that the blanking plug with valve for the DST800 does, in fact, work with the DST810.
Numbers off the stern light bulb are 1157 12V32/4CP
It appears to have the same style base as the others but is much smaller physically.
Numbers off the existing bulb are: 12v 25w ZP D1304 MiG p7
It looks like this is a 25W 12V BAY15D base bulb.
I came across this is a Jeanneau Owners group video on Facebook. This looks like it might be a nice solution.
I have not confirmed these are the correct handles, but they look correct.
Also check this site as it has a lot of info.
I still have to verify this, but this appears to be the 620x620 hatch in the main salon.
The lens is 626x626.
I have not verified this yet, but this appears to be the 500x500 hatch in the forward stateroom.
The size specified in the Jeanneau manual is actually the cutout size.
The lens is is 506x506mm.
Scroll down to the gasket section.
It looks like the 14x12mm one is the correct one. There is also a glue specified.
Search for Goiot 101711 for multiple sources.
I have not yet confirmed that these are the correct catch blocks. They look correct but I will have to verify.
For what they are, they are ridiculously expensive.
