Considering you have alterating time demands regarding your work, you could consider having likewise some alternation in your meditation program.
During the days you have less work, why not do aura cleaning twice a day and finish the session with pranyama and perhaps yoga? Breathing exercises do not take much time anyway as you can do them for something like five to ten minutes, or even less when beginning as to not overstrecth your capabilities. That is not to say that they can not be done for longer periods, but in this context let's keep it short.
After pranyama, you could do something else, like
Sat Kriya for 3 minutes and lay in corpse pose for 5 minutes afterwards. That would be less than 10 minutes, but would help your wellbeing.
Just some ideas here: You could also choose a few hatha poses, for example five, and stay in each pose for 30 to 60 seconds and at the end of it, lay down relaxing for five minutes. All done in less than 10 or 15 minutes. After these, or something similar you could try doing final Ritual, which also does not take much time - one round of final Ritual is around ten minutes or so, it really depends how you perform. Tetragrammaton ritual and shattering ritual would add some more time and effort, and perhaps those would be best left for another time, for now.
Summing it up, breathing exercises for around five minutes, and another 10-15 minutes for yoga, would be around 20 minutes. Does this sound unreasonable to you? To me it sounds like something you could pull off when you play your cards smartly.
You mentioned exercising at home, and I skimmed through the video you shared. In that video, the man shoved proper technique for squats, pushups and planks and it looks like a good short routine. You could alter doing that and the above practices depending on what day it is and how you feel.
During the days when you have to work for half a day you could still do the aura cleaning, aura of protection and void meditation twice per day, as it is recommended, but keeping it at that, not adding anything on top of that. I would recommend final Ritual as well, but given the situation it is probably better if you would reserve it to the days when you have more time, for the time being. So all in all if you spend around 10 minutes for ac and aop, plus five minutes for void meditation that times two would total 30 minutes per day. Surely you can spend at least that amount every day? You would still have around 11 hours and 30 minutes for everything else.
I am also a bit of perfectionist, but I have also learned to accept when something is good enough for something and set certain priorities. My advancement is more important than always acing some other activity, but balance has to be achieved, not neglecting everything else for my own self sake.
About being perfectionist: Learn to calm down in the moment, and focus on the task at hand. Just be there in the moment, and do the thing, let everything else just be. You can not, and will not be effectively doing multiple things at the same time before reaching demigod level anyway, so do not worry and do your best which should always be enough.
Ps. I like cats as well.
