My recommendation: Use Docker. No need to deal with all the gritty details. If needed, reverse-proxy it.

Guacamole is (in my experience) unfortunately rather inefficient concerning bandwidth.

You can’t compare it to Steam Link either, because that’s using H264 video compression. Guacamole does not use video compression.

A single 5K 24 bit bitmap is ~42 MiB. That’s a lot, even compressed and especially at reasonable frame rates.
