This probably way too simple but what about the French style Apple tart. You'd probably need to make two of them and serve with some really nice vanilla ice cream.

I love tarte au citron and also clafoutis. I think brulee would be a faff for so many. Proper French apple or apricot tart with a creme patisserie base is also lovely and much easier to prepare ahead than tarte tatin. I also really like a cheese board with fruit and strong coffee.
I may have to invent French afternoon tea now

Tart au citron, I made it last year using a Mary Berry recipe and it was great

Heston has a recipe for Tarte Tatin. Always works and always commented on as being scrummy. Can make in advance and warm in oven.

Thanks all. Ok, a tarte Tatin or citron. Or both . I must Google a fraisier as I don't know what that is! Yes, we have cheese planned for later too...and calvados

Fraisier looks amazing!

I would cheat and buy make enough macarons to make a tower - delicious and French and a table centrepiece

I've done 24 creme caramel in two yorkshire pudding tins.

Croque en buoche would be a classic
Cheeseboard with various French cheeses

Another vote for fruit tarts here. Apricot or plum works really well on a bed of frangipane. Or how about profiteroles?

Chocolate fondue?

With loads of fruit and marshmallows?

NOM!

French MIL always does apple tart when apples are in season and there is a crowd.
Ice cream profiteroles would be an easy option (assuming you buy ready made)

BTW in France cheese is served before dessert.
