Garage ridge beam

It depends entirely on how long the ridge beam will be end-to-end, which I don't think you have stated.
If your ridge beam was - say - 5 to 6m long, I suspect two 7x2s would deflect too much in the middle, causing the rafters to
push out on the wall plates.

It’s 2.3m clear span.

In that case I doubt you'll have a problem. Presumably it's a single garage with the ridge parallel to the
entrance?

Yep, exactly.

Yes, listen to Isambard, no need for triangulation with a ridge beam, purlins and that width garage.

Do I really need purlins with say 6x2 rafters? I’m pushing my luck now!

Not on that span.

Shame you're not a bit closer to me. I'm about to demolish a steel framed extension full of 3M lengths of ~130 x 180 UB.
