Uh, I'm not sure FPVs have all of the effects that you're discussing.
FPVs are significantly range limited (~10km), and have relatively small surveillance footprint. It's true that persistent ISR is significantly increasing the danger posed to all vehicles within the 10-30km (perhaps further) of the 'front line', but these are predominantly coming from different classes of drones.
And yes, while FPVs can be queued onto SPGs (or whatever) by these other drones, so can other means of fires (like traditional artillery). As a reminder, tube artillery can usually reach out to at least 20km.
I am not downplaying the impact that drones in general have, and I'm also not claiming that FPVs cannot significantly shape artillery operations within 5-10km of the front line.
Here's the rub - Russia is clearly cable to assembly company sized AFV elements (though not consistently) to attack. And yes, we see these attacks generally get repulsed (with significant FPV drone involvement). So we know that Ukrainian ISR + FPV combination (Ukraine has been limiting its artillery usage) can be overwhelmed in the deeper space - it is possible to mass company sized elements, and transit them through into the line of contact, reasonably intact.
There's no denying that PzH2000 is more survivable than Archer or Caesar (that is infact the entire point of Archer and Caesar - trade suitability and tactical mobility for strategic/operational mobility). But you're also missing like... M109? Like by numbers, there were more M109s donated than any other western platform.
Here's a report (in Polish) from a FO mission to correct HIMARS fire (sadly the drone was lost but the Russians had to send a fighter jet to shoot it down with a rocket): https://x.com/Aldohartwinska/status/1792838189494706220
FPV drones have been used at much longer ranges than that - it’s pretty well documented with videos that with repeater systems there’s now been strikes in excess of 25km using FPV, by both sides.
That’s not to downplay artillery though: you simply cannot deliver the volume of fires with drones that you can with tubes.

Yeah but that's the whole point thats been discussed in interested circles - the shift of the vulnerability of SPGs from the firing to the travel phase in absence of accompanying VSHORAD. (If they just had 2000 Gepards) And as Gunlorrys have to travel and fire on certain roads, that decreases the problem space.
For the M109, you are completely right. I missed that one.
I am not saying that tube artillery has a problem, but that ~10-20km around the line of contact seems to be the place you don't want to rely on mobility alone for survivability. Rheinmetall currently seems to be developing a 100km ranged base bleed grenade for 155mm pipes.
