Take calculus and physics, at least the introductory courses first. These can be applied to other fields and are not limiting. I found geology to be interesting but you might like the ocean or skies or some other natural science.

Overall I would advise to take the easiest classes possible to satisfy the requirements. I do not want you to limit your education, but architecture classes are demanding and you need to dedicate the majority of your time to architecture without being mentally exhausted from your other curriculum.

However, I saw another post of yours (I believe) and you were thinking of double majoring. If you realize after 1 year that architecture sucks and you want to major in another field (ie. engineering) check to see what core classes will be required to fulfill that major. If you would still have to take Physics and PreCalc, then perhaps enroll in those.

Furthermore, since UTSA Architecture is a pre-professional bachelors program, you will have to enroll in a Master's program (typically 2 years) at either UTSA or another school to ever become a licensed architect. As you stated, if you decide to obtain your Masters at another university, check with an advisor at another potential school (yes I know this is 4 years away, and you probably don't know where to attend) to see if a pre-professional bachelor's degree is all you need to enroll, or if you would have to satisfy additional core requirements (ie. PreCalc and Physics I & II)

Finally, most 2nd year architecture gateway programs have a weighted requirement of GPA in Architecture Studios, Architecture Portfolio, and overall GPA. Therefore, you should focus on your architecture classes, and don't enroll in the math and science classes that are the hardest, but the ones that interest you.

Easy answer:  Ones you can ACE without breaking a sweat.  For me calc and physics weren't so bad, but it was a grave mistake to take trig (professor was bad).  So look into who's teaching, and know your strengths.  We did have an option to take other maths like stats, or the one I should've taken, computer science.  Frankly, you're gonna forget most of the math by the time you graduate...

I went all the way to DiffEq and Linear Algebra during undergrad.

I don't regret it one bit. Yeah, tough courses, but the intuition that getting to that level of math gives you lasts forever. It's especially useful if you run very large quantitative program models in a planning setting (I work at a fairly large firm).
