I've tried seeking out this answer several times and even made a similar post about it here. Touhou games are just generally that difficult and many top players who have stared out also had a similar experience. Trying to learn the Touhou games can either be fun or miserable experience, I would suggest starting with a game that you find to be engaging and less infuriating. Perfect Cherry Blossom, & Imperishable Night are highly recommended games for beginners so you should try them out and see if you will enjoy trying to obtain a Normal 1cc.
Embodiment of Scarlet Devil is a game many players have started out with and recommended however, the later stages do become difficult and the game doesn't offer a lot of bombs to skip through some of these annoying sections. Mountain of Faith is another recommended game for beginners but I personally cannot recommend it to beginners cause trying to stockpile lives is kinda complex with some added risk to it, and Kanako is a very frustrating Stage 6 boss even on Easy Difficulty, and the continue system adds more salt to the wound. Also a thing that these two games have in common is that you can't get the good ending on Easy difficultly.
If you do eventually plan on playing Mountain of Faith, I would recommend using a mod that brings back the original continue system seen in the other games.
Avoid Subterranean Animism (Touhou 11), Undefined Fantastic Object (Touhou 12), & Legacy of Lunatic Kingdom (Touhou 15) are these are notable for very difficult and infuriating, Subterranea Animism really ruined my experience and view point with the Touhou games. I'm aware that Point Device mode exists in Lunatic Kingdom but it isn't a option when trying out the extra stage in the game.
I'm currently trying to Normal 1cc Mountain of Faith, and I was able to complete my blind run using only 2 continues.
One piece of advice I will offer is that if there's a certain spell card or section that you find to be unable to clear consistently then you're better off bombing through it.
