Ok I could test setups myself on a public server thanks to Cacatoes' collective administration of gameservers attempt. BIG THANKS for that great opportunity.
I tried the ones listed above and refined them.
I hope I post the complete setups I ended up with:
Domination with rocket only and free rj.
Only Aggressive is suitable. ctf_gate1 hardly is esp. as players did not get the goal of game at once
set g_instantgib 0
set g_rockets 1
set bot_minplayers 3
set g_spskill 2
set sv_hostname "^6ROFL ^1Aggressive ^5Domination"
set dmflags 1032
set g_gametype 12
set capturelimit 500
set g_maxGameClients 8
set nextmap map_restart
map aggressor
echo "^1DOM Server config loaded."
Next is rocket DM with free rj.
set d1 "map aggressor; set nextmap vstr d2"
set d2 "map blitzkrieg3; set nextmap vstr d3"
set d3 "map oa_rpg3dm2; set nextmap vstr d1"
set g_instantgib 0
set g_rockets 1
set bot_minplayers 4
set g_maxGameClients 8
set g_spskill 2
set sv_hostname "^6ROFL ^1Ro^8c^7k^3e^8t ^1DM"
set dmflags 1032
set g_gametype 0
set fraglimit 40
set capturelimit 8
set nextmap "vstr d1"
map aggressor
echo "^3DM Server config loaded."
Third is normal weapons CTF without push (also no rj :O)& slow down by weapon hits as this is way too much and favors camping/spamming over aim and strafing.
set d1 "map oa_bases3; set nextmap vstr d2;set g_knockback 0"
set d2 "map oasago2; set nextmap vstr d3;set g_knockback 0"
set d3 "map ps37ctf; set nextmap vstr d4;set g_knockback 0"
set d4 "map am_thornish; set nextmap vstr d5;set g_knockback 0"
set d5 "map oa_ctf4ish; set nextmap vstr d6;set g_knockback 0"
set d6 "map oa_ctf2; set nextmap vstr d7;set g_knockback 0"
set d7 "map ps9ctf; set nextmap vstr d8;set g_knockback 0"
set d8 "map pul1ctf; set nextmap vstr d1;set g_knockback 0"
set bot_minplayers 2
set sv_hostname "^6ROFL ^7Unstoppable ^1CTF"
set dmflags 64
set capturelimit 8
set nextmap "vstr d1"
set g_maxGameClients 16
set g_spskill 2
set g_gravityModifier 0.97
set g_instantgib 0
set g_rockets 0
set g_gametype 4
echo "^3CTF Server config loaded."
Also had simple instantgib CTF with g_knockback 0 and thus no teammate pushing.
So overall from my perspective the setups work pretty well and offer fun and good play.
Within short time they did not establish broadly though.
But maybe someone likes to adopt or alter from them.
