I only use free Square, whatever is what they are calling it, and it handles everything I can throw at it. We are only B&M with our garden center, but with our bakeries, we use Square for holiday pre-orders currently. We don't use Square there as it is a franchise and has to use the garbage POS they are contracted with.
I really don't know what features are designed for online vs. in-person, but I would say start with whatever free offerings you have offered by Square, and when you run into a roadblock or a cool feature you want, then consider upgrading.
