Did you have a look at sch_mqprio, which can be used along with either
netprio cgroup or netcls cgroup plus tc on clsact's egress side to set
the priority for mqprio mappings from application side? At leats ixgbe,
i40e, fm10k have offload support for it and a number of other nics. You
could also use cls_bpf for making the prio assignment if you need to
involve also other meta data from the skb (like mark or prio derived from
sockets, etc). Maybe it doesn't cover all of what you need, but could be
a start to extend upon?

Thanks,
Daniel
