I wonder if the high FC is causing an abnormally low pH reading?

Very good. Go in stages, letting the water circulate the Borax or baking soda for about an hour before re-testing as to not over-shoot too high on either item. Once the pH gets close to 7.2 you're in the safe zone. TA at least 50.
Your CC is a little elevated, but let's give the free chlorine and sunshine time to help reduce that. If the CCs remain 1.0 or get worse, let us know.

No, it's not high enough to skew the pH test. It also would have no impact on the TA.
New levels after borax and baking soda:
pH - 7.6
FC - 7
CC - 0
TA - 110
CH - 25
I think it’s time to open this pool is open for business?!?

Yes, go for it. 
Should I worry about the Calcium Hardness being low? Seems this is more important for plaster pools. No big deal to throw a bag in if necessary though.

With no plaster products in the water - no. The only other item that might require some CH is a heater, but it doesn't look like you have one. Now if you have some extra cal-hypo laying around and just want to use it up, no problem. Just be mindful of the CH level over time so it doesn't get too high.
Here is a comparison from my pool:
PH is mega super high because I just dumped a bunch of baking soda in to try and tweak my LSI. But anyway.
My guess is you have way way way way too much chlorine in which is affecting the PH reading to be invalid basically.

Here’s today’s for comparison.

What a success!! TFP and the TFPRO test kit with PoolMath has made my pool opening a huge success and a breeze. I had some serious anxiety about pool chemistry, but so far I have followed the TFP method with great results. Hopefully this isn’t just a honeymoon phase and my water isn’t going to turn on me soon. But thanks to TFP for getting me to this point!

It sounds like you have your pool open, so you likely came up with a solution. I would have bought the ladder / stairs that I want as my permanent stairs, and built a small temporary platform for them on the outside of the pool.
Timer question... Im running a 1.5hp 2 speed pump that has a rocker switch (middle is off, HI and Low). I am currently running the pump on a 12gauge extension cord rated for the appropriate amps. I will be hard wiring in the off season when we build the deck. Is there a timer I can use now with the extension cord setup that will run both speeds of the pump, and then reuse the same timer when we are hardwired?
What is your pumps voltage (120 or 240).
Iets assume that you have the correct size breaker and wiring out to your pump
You *could* wire in a two speed timer, and it could be set to run the pump at low speed during certain times, and high speed during others. However, the reality is that you will be running your pump at low speed all of the time except during "special occasions" - cleaning, adding chemicals in large amounts, etc.
You would be better off with your situation to have a regular timer and a manual Hi/Low switch. The time runs the pump on low when it is set to. When you want to vacuum, you manually turn on the timer, and flip the switch to high. When done you put the timer back to automatic and the switch to low.
Pump voltage is 120
Your second option seems most reasonable. Thank you for that suggestion!
Do you have any recommendations for a regular timer?

I used to use one similar to this - https://www.amazon.com/Intermatic-P1121-Aerators-Decorations-Landscape/dp/B003NVLWMI/ref=sr_1_9?dib=eyJ2IjoiMSJ9.zvjEYgHmUv4M1w3_plAbyHd7r49O9rZDE1Aafd2_kT1ithdEObVyaijLxUoUWZWGlZD5etvEzJLP0Y6MYR_n6xX3w95dThRfivINIvDWzM6SoypL-2L7eqmHYjqGFo_q9XwumuEzzFEhG5KfbaYzNcjJT-lY3NMJCr3Gt-VbS6PMJEmyqhBKQT-H6satf1cRTHFSyXH_H6bDZtvEcLuDLZTZI-5JROU5vA5cIjsTXiqNDj0KDoLiEYSt4DfbP0dbZY5dUmUD8Rb83yiPLjj10J5sg84ZG9cHnO7gF23zRqw.vU6xYAEVmRbwSVEgv9AJP1N14s6pCFivmYJjkrj4IkA&dib_tag=se&gad_source=1&hvadid=695038798970&hvdev=c&hvexpln=67&hvlocphy=9019657&hvnetw=g&hvocijid=7584612967468174766--&hvqmt=e&hvrand=7584612967468174766&hvtargid=kwd-337260537732&hydadcr=24660_13611807&keywords=120v+pool+timer&qid=1720458117&sr=8-9&th=1
I don't recall the exact make/model
Now I use the timer built into my Salt Cell controller
