Things are obviously different where you are then. Here customers are encouraged to join the staffed checkout queue with signage and staff directing people towards it. Direct access to the self checkouts is blocked off from all but one shopping aisle and two thirds of the self checkouts have been taken out of service to faciltate social distancing. As for scan and go, I have no idea what that is.
I think it'd depend on what your priority is - protecting staff or protecting other customers. Self checkouts are likely to be a spread vector as lots of people touch them (remember the thing about the Maccy's touch screens testing positive for human faeces?), but obviously if you're served by a human you may infect or be infected by them.
