Here are settings for 22 bots you can use for sabaki if you want a very strong opponent to play at your level. You need zen6, gtp4zen, katago 1.3.2. The rankings do not correspond to human rankings, you might have to play below your rank to win. Suggested minimum pc: i3 with gtx 1030 or higher. you can still buy zen6 if you didnt get it when it first came out:

For Katago, you need to create seperate config files for each bot (ex. "1d.cfg")
If you have zen 7 (not worth it, don't buy if you don't), you can add a few weaker bots if you need them:
zen7 17k -t1 -r3 -s200 -n0 -o4.0 -p0.2
zen7 16k -t1 -r3 -s200 -n0 -o3.0 -p0.25
zen7 15k -t1 -r3 -s300 -n0 -o2.4 -p0.3
zen7 14k -t1 -r3 -s300 -n0 -o2.2 -p0.3
I personally stream the pc to my likebook mars ereader through a remote desktop app. It's like playing go on a touch screen kindle instead of a computer. You can use bluetooth keyboard/trackpad/mouse as well. Because there are no time limits, you can also play the game out on a real board.
All bots can play on 9, 11, 13, or 19 boards, either chineses or Japanese rules and komis.
