Struggling with Riyaa in Daily Acts

Assalamu-Alaykum, I know Riyaa is a serious issue that can harm our faith, but it's something I constantly worry about in my actions. Even when I don't intend to show off, I can't shake the feeling that I might be doing things for others' approval instead of for Allah. Like when I'm leading salah and recite the Quran, I avoid making my voice beautiful even though I can, just because I'm scared it might turn into Riyaa. Even simple things, like having duas as my wallpaper, make me overthink-wondering if I only set it up so people might see and think I'm religious. Recently, I was in the car with a friend and we got tired of listening to music, so I played Surah Al-Baqarah for a bit. Though I meant it sincerely, I ended up questioning myself-why did I choose to play it only when my friend was there? I don't usually listen to the Quran in the car alone. Any advice on dealing with this would be really helpful, jazakAllah khair!
