In general, you can read the advantages/disadvantages of each congestion avoidance algorithm here:

You can try whether CTCP works better or BBR2 for your connection.
Other than that, smaller packets work a bit faster, but only if there is no packet coalescing, and it may depend on the game/protocol.
I also think it is beneficial to tune the network adapter settings, rather than just focusing just on the TCP/IP protocol settings, see these:

I hope this helps.
