Catalyst 9500-24Y4C Core with virtual stacking design question

Hi everyone, we will be replacing our current core (4900M) and layer 2 switches (3750X) with C9500-24Y4C with advantage license and same for the L2 switches with another pair of C9500-24Y4C with essentials license. Currently we are doing HSRP on the cores for all SVI's. I was looking into doing stackwise virtual on the new cores instead to try to eliminate spanning-tree so wanted your opinions if that is something you recommend. Also, for the new L2 switches, since they don't have the advantage license I will need to set those up as standalone switches connecting back to the core so my question is that servers connecting to these will have one link going to each so will that cause any layer 2 issues since there isn't going to be any spanning-tree config? Thank you.
