any reason not to use WiFi, e.g. much simpler to use ESP-NOW

Check the library samples or just google, make sure you know the difference between Classic and BLE, which does you board have?

Classic Buetooth(SPP protocol) is not implemented on all esp32 modules. What model of esp32 so you have?

If you use the Espressif product selector here
https://products.espressif.com/#/product-selector?names=

Then under the bluetooth pull down check the box for BR/EDR + Bluetooth LE v4.2 and you will see the chips with classic bluetooth.

actually its for my college project, and I recently know about esp now. I feel like I will go with it.
I have very limited time, how hard is it to learn esp now. I am trying to build a remote control car.

fairly straightforward - in fact a lot simpler than BLE!
select Tools>Board "ESP32 Dev Module" and have a look at example code File>Examples>ESP-NOW
