Congratulations mismck! Your explanation highlighted a few mistakes I made so it's really helpful.
I'm going to share my plan too as I think if someone combined the strategies they could get an even faster score, and it's also useful to see the difference that a few wrong choices might make.
Hedwig Handy also chose Nerd Brain for the Quick Learner bonus trait. For traits I gave her cheerful (to stay happy), and wasn't sure for others so ended up with Slob (so she wouldn't worry about getting stinky when I neglected her needs), and Genius (for the focused moodlet but this was irrelevant as she was always confident from upgrading). Having High School Years for Overachiever would have been helpful and am annoyed that I forgot about Insider considering she would be in a club hangout the whole time.
Moved her into a small lot in Bridgeview, Newcrest so the home lot was the only one in the neighbourhood. Created a 2x2 room for requirements and made it a micro home. Set Homey (faster handiness skill) as a lot trait but somehow forgot Study Spot. She bought a stereo, five woodworking tables, a focus lamp, and a triangle bath.
Like Tina she went straight to befriend Bjorn Bjergsen and take over the Good Timers Club. Club activities were set to woodworking, being friendly, listening to music, and dancing. Eventually bought handiness boost as a club reward but I think Hedwig was nearly maxed in handiness by then anyway. She also used the Bjergsen's computer to order all the upgrade parts she'd need (approx 60 common, 12 electronic, 20 kitchen, 20 plumbing) there was no need to keep simoleons for anything else so she bought extras of everything.
Once she returned home she started a club hangout and invited over a repairperson who was immediately added to the club. In this game it was a lovely chap called Krishna. Hedwig made sculptures etc. on the woodworking table and asked Krishna to mentor her. I did this up to level seven handiness for the quick bathroom upgrades thinking this would be enough given I was focusing on those types. I'm now thinking it would have been worthwhile levelling to 10 for the remaining kitchen upgrades as there are not 23 bathroom ones. Alternatively I could have started with all the bathroom upgrades while levelling up to 10 for the kitchen ones. There may have also been better options for upgrades but didn't have the patience to test everything
Here are the upgrades completed. Not in order other than the first because I can't handle that much direction.

Observations:* This kind of challenge definitely benefits from having more packs. For the location options plus different traits and possibly different upgrades (I think there were some toilet upgrades I might have used had I Eco Living installed)
* Sims walk slow. I tried to make as many upgrades as close to the front of the lot as possible but some couldn't be avoided. Bjorn for example started in the gym area of his home which is the furthest from the door adding valuable minutes to go upstairs to meet him/ have him walk down.
* Apartments are glitching out for me at the moment. Otherwise I think doing the second upgrade on the Feng's triangle bath (had either of them appeared in the group pool) might have been quicker than a talking toilet upgrade in Stargazer Lounge for the Uptown neighbourhood
* From looking at previous challenges the Install Surge Protector in a neon sign at Paddywacks Emporium was listed as a quick upgrade but I couldn't work out what to upgrade when I went there to test. If anyone could share a screenshot of what sign to upgrade that would be super helpful.
* Was setting being friendly as a club activity a bad idea? Sometimes her clubmates talked to her while she was upgrading and this might have slowed her down a little.
