If you have a regen in progress it's better to do a short drive, the ECU will only run a regen at idle for about 5 minutes before bringing it to a controlled halt - it will start again next drive as soon as it can.
It's still very much worth letting it do that, if you just turn off then everything is at a high temperature and the excess fuel injected to get those temperatures can drain into the oil sump while parked.
That's the difference with a forced regen - it will try and complete no matter what and as noted things will get very hot. Keep that in mind this summer if you park up in a handy layby to save disturbing the neighbours - check for tinder dry vegetation and rubbish!
I monitor mine on long trips using VAG DPF and try to keep in the habit of dropping a couple of gears and getting the revs up to about 3k to both help the temperature and put the engine under load occasionally.
Your regen times/distances seem largely the same as mine. No harm in doing the research and making a plan but I'd leave it alone for now your first clue it's actually full will be when those start happening more frequently.
