Those are all very great points but the first one really resonated with me, as I started working on weekly charts instead of daily charts, and everything is just a lot better now.
Weekly is better because your technical may coincidentally align with fundamentals without using fundamentals at all. However, you should be afraid the robustness of your trading system using weekly timeframe if it doesn't have edge in other timeframes. Try search robustness test (upper and lower timeframes).
I actually looked into that and it doesn't apply to time frames of H4 and lower, it just gets confusing from there on but the profits have been looking better now.
I feel like holding positions for that long works a lot better for stocks and crypto-only, I think we can all agree that the promise of quick profits in markets like pairs on shorter time frames can be appeasing but it really can't be guaranteed thing too since it's difficult to get, at least that's how it was to me, plus I don't make a lot outside of this to even consider holding positions and assets for periods longer than let's say a month.Hey, welcome to the dark side! Just don't let the daytraders hear you, keep it on the down low!
All kidding aside, I pushed the holding period to what most here would consider extreme. The longer the holding period the more profitable it has become for me after I finally learned to be patient and hold positions for years. Here's an example if you're interested:

Does the methodology work on multiple instruments? Anyway, what instrument do you trade?
