if you are just hedging french living expenses ( as I currently am ) I use buying euros in my fido brokerage, and I use moneycorp.com to hold euro , pound sterling , and dollars.

I can exchange opportunistically beyween the currencies I need. This really helped when I was buying my house 2 years ago.
the advantage also is that its a US based account so you dont have to declare it over 10K$ on any one day in the year to IRA.

I did open a french bankaccount (a lengthy process) to direct debit my house bills etcfrom, but have to manage that it doesnt go over 10. though , going forward I may just take on that hassle again. however you can pay all french bills direct from moneycorp in euros. They also have real people at the end of their phone line, which was very helpful when a glitch happened.

hope this is helpful.
PS make sure you have a CC with reimbursed foreign fees. Visa travel rewards is ok, and fido debit. the 2 way banking fees have gotten out of control since covid.
