what would a curriculum of books look like taking me from the most basic mathematics to quantum physics?

Quantum physics is just a ploy based on questionable experiment evidence. It serves to undermine the potential existence of an absolute truth by gnawing at the roots. It obfuscates physics behind a seeming-contradictory mix of catchy pop-sci ideas and dissonant jargon-heavy theories.

Quantum mechanics is taught to undergrads. It’s not the mysterious incomprehensible pile of magical mathematics that self-help and quantum woo books peddle it as.

There are two fundamental parts to learning quantum mechanics at the undergrad level. The easiest to self teach is how to shut up and calculate, which is just being able to use the axioms associated with the theory to make relevant calculations. All you need to get started is calculus 3, basic differentials, and a cursory understanding of inner product spaces / eigendecomposition.
The harder part is getting used to the setting in which you are doing calculations, which is the unintuitive part of quantum mechanics. This will involve going through many discussions and examinations of Stern-Gerlach, CHSH, etc., to get a qualitative understanding of the idiosyncrasies of the theory.

You can self study both - they're not 'hard' at the undergrad level at the very least - but you need to be a bit careful.

If I already have a pretty strong background in math, what is the best book to jump into physics? Nearing undergrad degree in stats. Seen some physics from high school courses in mechanics and electricity (Maxwell's equations and stuff).

I'd like to work from the fundamental forces up if feasible.

Do a survey through university physics (the standard book) to get everything from basic mechanics to basic atomic physics. The problems are good, the math easy, but they still stress understanding the physics.
After that, you'll be able to look up any standard list in google to study topics of your liking. I like 't Hooft's "how to be a GOOD theoretical physicist" but you should cross reference with stackexchange and other online lists. Common good names that show up are jackson, griffiths, arnold. etc.

I suppose you can learn Newtonian mechanics as well, but I don't think it is actually necessary to learn newton's laws to learn quantum mechanics.

Don't even bother with fundamental interactions. The Standard Model covers that. If you want to learn SM you'll need to learn Quantum Field Theory. If you want to learn QFT you'll need to learn quantum mechanics and special relativity. Quantum is not about fundamental particles, rather it is about describing the behaviour of atomic and subatomic systems. AMO and Condensed Matter physicists use QM all the time and don't know a thing about QFT, because it's irrelevant to them.

we are using QFT increasingly often and I know as a fact my condensed matter colleagues use QFT already. A lot of their research is on simulating field theories with CM systems

Complex analysis and PDE aren't necessary, if you stick to very basic QM books like Griffiths or Shankar. Why even recommend both of them? They are practically the same.

Yes, but you won't learning it because:

1. It's a lot of work.
2. It's theoretical to the point that none of it can be practically applied to improving any aspect of your life unless you happen to be a scientist working in a field where quantum mechanics is relevant
3. There are other things you could spend your time learning that will improve your life and take considerably less time

Quantum for Mathematician books require way more analysis knowledge than spivak. And everyone who skips intro physics regrets it.

Quoted By:

Quantum physics is flawled-Schrödinger equation just comes from somewhere. Nobody can derive it, its taken as a fact: an axiom.

The mathematics is just probability theory. You have to multiply the wave fuction by its complex conjugate and integrate the multiple by all space so you get the factor that makes the wave fuction times complex conjugate equal to one when all space is integrated. Then you can do tricks to this probability function e.g. calculating most propable position of a particle in potential field.
