- Zoom out even more than allowed? I only get 75% zoom and I feel like it is still so close.
Zooming on PC isn't really like mobile. The good news is that PC allows for modding! The bad news is I don't know of a zoom mod that's been updated for 1.5, but that doesn't mean there isn't one. And if there isn't, one will be updated soon enough. You can ask in the Modding Discussion section.
- Is it posible to enable automatic fighting?
I'd strongly suggest giving combat a try on PC. It's much, much easier compared to mobile once you get the hang out it. If you do give it a shot and find it's not for you, there's always the Auto Attack mod:

- AND MOST IMPORTANT, on mobile when you click a rock it switches automatic to the pick and then on a log and switch to the axe, is this not possible on pc?? I will die
Again, not available on PC. I recommend keeping your tools in the top row of your inventory and using the number keys or mouse scroll wheel to switch between them. If it's not something you're used to, it will take some time, but you can get to a point where you don't even think about switching tools. If you really can't get used to tool switching, there again is a mod for this:

It's interesting, these features only exist on mobile because the touch controls on that platform are far less optimal for the game, but it's very common for people to miss them if that's what they're used to. I promise that the controls on PC are designed such that these features aren't necessary for most people (everyone is different and for some these features are genuinely necessary, of course). If you have an interest in trying other PC games at some point, being familiar with the PC controls of Stardew will help a lot there. And not every game has the wealth of mods Stardew does :)
Edit: You did say you are new to PC, and I shouldn't have just linked to mods without providing the wiki's guide for getting started with modding:
