Welcome to France!
Adapters are OK, up to a point, for low power items and those, like chargers, where the electronics and plug are all one integrated unit.
If you are bringing any larger or high powered appliances - dishwashers, washing machines, kettles, toasters etc these really should be switched over to French plugs, either by replacing the plug or, preferably for this type of appliance, the whole power cord - but you need to be confidant and competent to do the latter if it is a captive cord (or get an electrician). As Mat says the adapters are a fire risk for high power stuff.
After that - anything with a plug in cord - i.e IEC(kettle), clover-leaf or two-pin “Phillips” style can just have the cord changed.
Ours is just a “maison secondaire” so we make use of adapters quite a bit for lower power items which were bought in the UK and which conceivably could go back and stuff which travels with us but all the high power stuff has been converted except power tools as they might well go back home at some point and only get used in short bursts. As Mat suggested I have a trailing socket with a 4-way UK strip and a French plug on a decent cord for those.
Mat also makes the point that they are ugly - which they are but not as ugly as converters which go from a UK wall socket to a French socket. Nor are they as ugly (to my mind) as any of the re-wireable French plugs that I have found (I mostly used cords with a moulded French plug on one end and bare wires on the other and replaced the whole appliance cord).
I’d add, however, that they are inconvenient - you are bound to quickly acquire items with French plugs so you can’t just put a UK adapter in each socket and have done - you’ll be swapping the ****** things in and out and, despite having dozens, you’ll never be able to find one when you need.
As for the pile of UK plugs - bin them, everything comes with a moulded plug anyway.
