Plant out or not at this time of year

So I was filling my winter baskets and the garden centre had a bunch of hebe and Heather and herbs (got sage, rosemary and thyme) at big discounts, like £2 a plant so I picked some up. I know there’s a chance they won’t survive the winter if they’re not established now but what would give the best chance- leaving in plastic pots, potting up into proper pots or putting in the ground?

Only other thing is, I’ve not really planned my beds yet… so if they go in the ground, I may want to move them next year, would this kill them?

I’m in the midlands, south facing garden but with trees/fences it doesn’t get much sun at this time.
