> though I’d need to use another device for web browsing and for handling modern file formats

Have you tried running something xquartz and have, say, firefox running on sone other computer on the network? As long as you’re on a fast lan with low noise (basically cable gigabit ethernet?) it should be mostly okay? You’d have to redirect audio as well though…

What's the best, most seamless option for this kind of LAN-hosted browser? X11 forwarding, Apache Guacamole, something else?

X11 (no forwarding, it’s really meant to be that way - originally at least) would be the simplest and lightest. If you’re on a private lan you might also turn off cryptography… the powerpc cpu probably either has no crypto acceleration or acceleration for old cyphers.

Other solutions might work… guacamole could work but would use a whole other desktop (whereas x11 would still have some resemblance of integration).

If you’re okay with remoting the whole desktop, xrdp and vnc are also options…

I’ve found that modern X11 toolkits are more bitmap-oriented, so they benefit from ssh’s forwarding with compression enabled, even in gigabit LAN scenarios.

Best setup, specially for browsing, would be ssh or any other way to enable compression, but with null cipher.
