Fitting Floor & Doors New Build

I'm coming to the stage where I will be installing flooring and internal doors in our new build. Am I best to lay flooring first, which will be a combination of semi-solid wood and tiles and possibly some carpet, or should the internal doors be hung first?

My main concern is getting the best fitting on the timber floor around doors and also where the timber meets other floor covering.

You are best hanging the frames first then putting in the floors then hanging the doors so you can get them planed if required
