If the carpet is definitely going and being replaced with new, then it is better to decorate first. Emulsion first, beginning with the ceiling then the walls if painting them too, and doors, followed by glossing skirting boards and sills. Any rubbing down done prior to any painting of course. Then everything is all sparkling and fresh ready for the new flooring.
(We’ve cheated with the skirting boards and replaced the ones downstairs with ones that don’t need painting or varnishing, and will do the same upstairs as we replace carpets - cuts out lots of painting).
Wooden floors are very easy to keep clean, and can be brightened up with a rug here and there if you want (though not where they might be a trip hazard, of course). They are warm, too, but certainly, flooring type is a personal preference, and we all have our own likes and dislikes.
Enjoy your new look ?.
