I went through school in the days before Amazon, and more than once bought a few of my local stores out of 3x5 cards to make flashcards with.
Your scrub 'uniform' (military guy, we prescribed required wear and accessories as uniform requirements) should always include a pen, a backup pen, a sharpie, a good pair of scissors, and something to jot notes on. Always.
You want a good reliable watch with a second hand/counter.
If you find yourself on night rotations, a small flashlight comes in super handy.
You want a good stethoscope, but don't break the bank until you know what you like, and until you learn how to properly use it, an expensive one is just money wasted (flip side is if you can afford it, a properly cared for expensive stethoscope will outlast your career with occasional part replacements)
Shoes - everyone will have an opinion on what to wear, and what not to wear. The reality is nobody knows your feet like you do, and none of us know what your institutional policies will allow (for the record, I've worn crocs at work since 2006). Along this, some will swear by compression socks. I have no input on this, I've never worn them.
As you go, you'll find what you will actually use, and what you never touch. Wait until you get going and watch what your preceptors are always reaching for/using, and plan accordingly. Some folks love X, some folks in the same department hate X.
Most importantly, bring an open mind and a hard work ethic. Ask all the questions, take all the notes.
edit - keep a dry pair of socks in your backpack, just in case. Few things worse than having a patient...contaminate...your socks through your shoes, and you don't have any way to deal with it. Mostly applicable to ER and ICU rotations, but you never know.
For a poor mans diffuser try a ping pong ball with a slit cut in it to hold the light.
Works fine for LED keychain lights eg https://www.amazon.com/Uniclife-Keychain-Flashlight-Ultra-Bright/dp/B07KS7MHRD/ref=sr_1_6?crid=BWEDJMAHN1UQ&keywords=led+keychain+light&qid=1643143856&sprefix=led+keychain%2Caps%2C149&sr=8-6
