I meant to mention this, likely you will be required to have a actual electrician install the new weatherhead, meter box and main service disconnect. There is no reason IMHO that you cannot do the rest of it, although you may want a pro for the 220 stuff; ac, stove etc. This is why I get chummy with the guys at the electrical supply house, once they know you are not an idiot(read wiring simplified so you can use the right words) a case of beer and couple of hundred dollar bills go a long way. YMMV.
The NEC states that wiring should be done in a “neat and workman like manner”. I take this to the extreme. Leave lots of extra wire at the panel, strip the jacket back as far as possible, lay in grounds to the left buss bar, neutrals to the right and last do the hots. Bend all your wires at 90 deg angles around the panel and trim to fit. This is OCD and not required but IME no inspector will red tag it, they will know you did the work but will pass it because you did it so neatly and safely. Bonus the next person to open the panel will know exactly what you did because you labeled it as you went and it is easy to sort visually.
If that’s an open attic it would be easy to run the wires yourself. GFCI kitchens and bathrooms and put in a 200 amp service.
To add a new outlet find the stud you want to use and then use a thin drill bit to drill into the ceiling at the wall edge. That way you can stick a marker flag up into the attic to see where to drill a feed hole into the top board of the wall. the small hole in the ceiling is easy to patch and saves a lot of time.
If you do it yourself check the codes. Many areas now require some kind of safety outlet that prevents kids from inserting stuff into them. I know someone who had to replace all the outlets in a garage because of this.
finally, don’t forget about the attic. You could put in enough service for powered roof vents and a whole house attic fan. You could also look into pre-wiring for solar.
I don’t know if you’re considering doing this yourself, StGermian, but I will say that I completely rewired our last house by myself (except the service entrance) and it was much easier than I expected it to be. I had very little electrical experience before I started. However, the walls were open, which simplifies things a lot. I’d rather do electrical work than plumbing, any day. Even 220 is no big deal. I’d say the materials ended up being under $500.
My 1918 house had the original knob and tube until a kitchen fire in 1961, whereupon new wiring was installed, so I know exactly what was used in SF in 1961 - it was 3 wire romex - an early iteration, it may have still had cloth insulation. I’m no longer in the place, and haven’'t seen the wire in over a decade.
First - is the existing wire usable? If so, you just dodged a large bullet
Second - are the existing outlets enough? You may want additional outlets and/or light fixtures.
Third - trivia. A refer must be on a dedicated circuit (and maybe a 20 amp one at that). This was probably not required in 1961 (you don’t want a shorted table lamp tripping a c/b on the fridge and taking out the refrigeration (esp. on vacation)).
If everything breaks right, you may get away with just a service upgrade.
