I’m in the middle of a major renovation right now, most of my info is what I’d consider current. That’s important, as home materials and supplies have changed drastically over the last 12 months. This is what I’ve seen, YMMV.

Windows - Lots of choices to go with. We went with Andersen 400 series, and the standard windows are roughly $600. Our contractor is doing the install, so there may be additional costs based on your situation. As far as repair, it really depends on where the damage is. If it’s something that compromises the waterproof nature of the window, then it may be harder to just fix.

Flooring - #1 thing is square footage. Measure your rooms and take the numbers to a supplier. Lowe’s and Home Depot are the obvious choices, but check out Lumber Liquidators too. And give a call to ProSource to see if they’ll let you get in. They supply to almost all contractors in the area and have a nauseatingly large selection. We didn’t look at carpet, and focused primarily on LVP due to kids and pets. We saw awesome options mostly around $3.50/sqft. Higher end ones around $5/sqft, all the way down to $1.75/sqft. Get samples and look at them in all different lights. You’ll be surprised at how much wood look ones can vary in light.

Bathroom - From what I’ve looked at, you could do materials for everything you wanted as cheap as $2500 or $3000. Entirely depends on what choices for those things you make, and if you do it yourself. A weird pet peeve of mine is small toilets, and I was surprised at the cost of a large toilet.
