How do I need to think to play like White in this game? And why did Black lose when he did not play a bad move? Any advice for black would be appreciated.

PS: Why did White move the rook on f1 to e1 instead of developing the bishop on c1 on move 9?

move 9 was to free whites rook( on f1 it does nothing, and on e1 ot can support pawn and all stuff, bishop developing is good, but has no concrate purpose.
black lost, because of 2 innaccuracies( by Precise game on botjh sides , that is enought to win)
their second inaccuracy with bishop move, trapped their own rook, so they lost it, and white had pressed it wirh rooks vs bishop advantage
black first inaccuracy was 29 that they made natural bishop pawn bound, instead of important strategical b 4 pawn improvement( SF recommends R a3, which allows to push that b4 pawn later, and built black pressure around it, and B c3 just blocks that possibility, and all pieces has less freedom in the End

A single analysis is not enough, but it's good enough.

Move 29.... (0.81 1.55) Inaccuracy.
Better: 29...Ra3 30.Bc4

move 44... (2.20 3.47) Inaccuracy.
Better : 44...b3 45.cxb3 Rb4 46.Bc6 Rxb7 47.Bxb7 Kf8 48.Ke2 Ke7 49.Be1 Bd4 50.b4 Nd7 51.g4

move 61... Blunder. Checkmate is now unavoidable.
61...Kg5 62.Rf6 Kg4 63.Rxf4+ Kg5 64.Ra4 Kg6 65.Ke6 Kg5 66.Re4 Kg6 67.Rg4+ Kh5 68.Kf5

White
0 inaccuracies
0 mistakes
0 blunders
8 Average centipawn loss
98% Accuracy

Black
2 inaccuracies
0 mistakes
0 blunders
22 Average centipawn loss
95% Accuracy

If you @tyangun re-analyse the same game on a different computer, GUI or engine, you will find different assessments of the game. Try it on Lucaschess, and play with the analysis settings. Squeeze out all the possible flaws out of the game. There is nothing more satisfying than trying to do it your self.

To me, it seems like black isn't thinking well strategically.

... b4 doesn't seem like a good idea - I don't know the opening well, but this seems like a strategic mistake. I think black is over-extending. Maybe there's an argument for the minority attack in the Sicilian, but I would assume that argument would apply when the pawns aren't quite as weak as they become here, and possibly after black has castled. There are 3 master games in this position and they all go 10. ... Ng6.
... Qxa7 seems like a weak attempt - better not to trade the queens when a pawn down, especially with that weak b4 pawn

Also notable is the fact that black's chess.com account was closed for Fair Play violation. If this is you, or indeed a friend of yours, presumably you know whether/how they were violating chess.com's Fair Play Policy.

If they were cheating using low-depth stockfish, a better question would be "What are the weanesses of low-depth stockfish and how would you exploit them in a 10-minute game?", which to me is a pretty interesting question. In this case, I'm not sure the advice "don't cheat" would help, but it is the advice I would give. Note that I'm not accusing them of cheating, just noting that that's one way they could have violated chess.com's Fair Play Policy. It could also have been something else, or indeed a false positive.

If they weren't cheating, I would note that engine analysis doesn't seem to be very helpful for this game - the analysis you provide seems to suggest that moves 29 and 44 are the inaccuracies on black's part, whereas I would notice that directly before black's 29th move, they are playing against 2 bishops, down a pawn and without a particularly attractive place for their knight. All of which is pretty hard to play, so I would probably analyse this as quite a bit worse than the +0.8 the engine seems to give. Maybe as a computer you know that after a precise sequence of moves starting Ra3 you're fine, but that doesn't seem like a very human thing to think, to me at least.

White seems to play very well this game - if I knew how to play like white I would be doing it.
