I got a full panel before starting and a repeat at three months, and the second one is more useful than the first purely because I now have something to compare against.
The bit I cannot resolve on my own is how often to repeat it, because quarterly seems to be the convention and I cannot find the reasoning.
I have searched first, so if this is covered somewhere point me at it and I will read it.
Short answer first, then the reasoning. Quarterly for the first year is convention rather than evidence, and it is defensible for a simple reason: it is roughly the interval over which HbA1c becomes informative again, since it reflects about three months of glycaemia. After the first year, and once doses are stable, annual is reasonable unless something specific is being followed.

That is correct as far as it goes, and here is where it stops going. One addition: if the lab changes analytical platform between your draws, the comparison breaks and nobody tells you. It is worth asking when a value moves inexplicably.

Same position here, arrived at the long way round. A defensible baseline is short: HbA1c and fasting glucose, a lipid panel with ApoB if you can get it, ALT and AST, creatinine with eGFR, TSH, ferritin and B12, and a full blood count. That set catches the things that change, the things that explain symptoms, and the things that alter the prescribing decision. Almost everything else on the long circulating lists is either invariant, uninterpretable without a specific question, or an incidental finding waiting to cause an unnecessary workup.
Adding the clinical framing, because it changes how the question reads.
PSA: get baseline labs BEFORE starting baseline bloodwork therapy. You need a "before" picture to measure progress. My recommended pre-treatment panel:
