Compute Engine doesn't really have "Instance Types" or "Instance Families" per say, just Core/Memory combinations. Larger machines have a higher chance of preemption though (according to the PM of PVMs who stated that on this thread). There are a few interesting projects out there that do the kind of automation you are speaking of like these: https://github.com/binary-com/gce-manager https://github.com/binary-com/gce-manager https://github.com/skelterjohn/prevmtable https://github.com/skelterjohn/prevmtable Spreading multiple smaller machines over a multi-zone k8s deployment might help mitigate, but it will never solve all the issues.
