What climbers could I grow in pots to train on a fence panel like this?

Please excuse the bookie drawing, haha.

I am installing a fence panel like this 180x180cm and want to go for one with a trellis section at the top for climbers.

However, due to the patio I can’t plant climbers in the ground.

Which ones would be good in big pots? How big would the pots need to be to encourage decent growth?

It’s technically south facing but will be in a corner with probably 60% sun on a sunny day.

All my research has just said “can be grown in pots but better in the ground”.

Is there anything that wouldn’t get too massive and wouldn’t mind a pot?

Preferably flowery and colourful but ultimately anything that would grow the best.

I already have a clematis in the ground elsewhere so something different would be nice.

Cheers
