Did my first fall lawn renovation. Now I wait and hope it comes in well/

I bought this house in Minneapolis late last summer and the lawn was in pretty bad shape. I did not have enough time to do any of this last fall, so I attempted some fixes in the spring. The back yard was at least 50% creeping charlie. I killed that using a couple different products, rented a power rake from Home Depot, and tore up the dead material. I seeded Scott's Sun & Shade before I knew much about lawncare. Overall, the backyard came in pretty well and I was mostly happy with it.

The front yard had some creeping charlie and some wild violet that I also killed with the same products and used the same power rake and seed. It filled in those patches pretty well, but through the summer, I quickly noticed that a lot of my front lawn was some type of grassy weed I could never quite identify. I am pretty confident it can't be killed by a selective herbicide, and I hated how it looked. It was lighter in color than my turf grass and grew a lot faster.

After spending a lot of time this summer learning, I planned a full renovation for the front yard and a partial renovation for the back yard for the fall.

Front Yard

1. Killed the entire thing with glyphosate.
2. Raked up as much of the dead material as I could using a garden rake and a Groundskeeper II.
3. Core aerated by hand using a Landzie manual fork aerator.
4. Spread about 2.5 cubic yards of top soil using a garden rake and Landzie lawn leveler to level the yard. It had a ton of uneven spots that are so much better now.
5. Spread Twin City Seed Blue Resilience that I had pre-germinated / primed for 4 days prior to get a bit of a head start then mixed with Sustane 4-6-4 starter fertilizer.
6. Covered with about 1/8"-1/4" of screened compost using a Landzie compost spreader.

Back Yard

1. Treated with Tenacity about a month ago.
2. Dethatched with my Groundskeeper II. I was actually really surprised by how much dead material I raked up with this!
3. Core aerated by hand.
4. Scalped the lawn to just over 1" tall.
5. Spread about 0.5 cubic yards of top soil. It had a trench going from my house to my garage where they had buried the power line to my garage and a ton of divots and low spots.
6. Spread the same TCS seed.
7. Covered with the same 1/8"-1/4" of screened compost.

I have a sprinkler set up for each yard and a wifi timer running 6 times a day to keep it moist until I see full germination. I put so much work into this, so I really hope it grows nicely. The yards will look so much better after this finally fills out, and I'm very excited to see the end product!

A couple questions for people:

1. Should I put some Sustane 18-1-8 +Fe fertilizer down in a month or so when the new grass is growing well, or wait until the spring to fertilize again?
2. Any guesses as to when I should start seeing germination? TCS says it germinates in 7-10 days under optimum conditions. So does that mean 3-6 days since I pre-germinated for 4? Also from my understanding, 10 days is pretty fast for a kentucky bluegrass. Is this just a quick to germinate cultivar or is that timeline just for the tall fescue?
3. Do you think I should look to overseed patchy areas in the spring, or should I focus on fertilizing and pre-emergents to keep weeds down and give the bluegrass the summer to fill in?
4. Any other tips to give me the best chance at success?

Note: I swear this isn't a Landzie ad, but when I did my research on each of those products, their version kept coming up as some of the best quality and they had some solid sales during Prime Days this summer.
