Great question — answering as the UphillTech team:
Most folks I know who are working with the Linux network stack use the below diagram (which you can find on Wikipedia under CC BY-SA 3.0 license). As you can see, in addition to the netfilter hooks, it also documents XFRM processing points and some eBPF hook points. tc eBPF programs would be executed as part of the ingress and egress qdiscs. BPF networking hook points other than XDP and tc (e.g., at the socket level) are not documented here. As far as I know, IPVS is built on top of netfilter so it wouldn't directly appear here.
