i'm totally lost trying to deploy my first react app, any simple deployment strategies?

hey everyone, i just finished my very first react app, it's a super basic todo list with a tiny express backend and i'm so excited to finally get it out there. but man, app deployment is kicking my butt. i've been looking at netlify, vercel, heroku, even aws s3 for the frontend and ec2 for the backend, but it's all just so much information for a complete newbie like me, honestly it's overwhelming. i'm really not sure what the best way is to get this thing live without breaking the bank or spending weeeks on setup. what are some realy straightforward, beginner-friendly options for deployment strategies for both the react frontend and that small express backend? i'm talking like, 'click this, then click that' kind of simple if possible. i don't need anything super scalable right now, just something reliable to show off my work. also, any common mistakes i should watch out for when doing my first app deployment? help a brother out please...
