I would like to ask for help confirming my schematic for a final project. The design is a custom ESP32 Pomodoro timer that needs to send data via Bluetooth, display the time on an OLED, and manage power from either USB or a battery. Could you check if my connections will work?

When I create the first version of these simple boards I never go for perfection - perfection takes a lot of time and effort. For simple and cheap boards, you can just build it, fix it and build it again. Much faster and easier approach. Just be sure, when you do layout you have access to all the important nets ... and if you are not sure, just add some extra 0R resistors so you can simply cut or wire up the things if something is wrong.
I know this does not answer your question about your schematic, but it is important that everyone gets confidence that they can design boards by themselves. hope this helps
