Yes, sanding wood before staining is essential in a cabinet project to ensure a smooth and even finish. Sanding removes imperfections, opens up the wood pores for better stain absorption, and prepares the surface for a more uniform application of the stain.

No, you have to sand. You have to get the top coat of the finish off so the wood will take the stain. Otherwise it just wipes right off. However, they do make polyurethanes that have built-in coloring that you could put on top. But I don't think they're intended for flooring.

Let water-based stains dry for two to three hours and oil-based stains for four to six hours before applying a polyurethane sealer. The best way to get a smooth finish is to apply the first coat of sealer, let it dry, and then lightly sand the surface with 220-grit sandpaper before applying a second coat.
Sandless refinishing involves lightly buffing or screening the hardwood floors and applying a coat of polyurethane. Unlike traditional sanding methods, this process minimally affects the floor's surface while providing a rejuvenated look.
Just lightly scuff the surface to give it some “tooth” so the gel stain will have the best adhesion.
Before applying polyurethane, it's crucial to clean and sand the hardwood floor thoroughly.
Oil-based interior stain is what most people think of when it comes to wood stain. They are readily available and the easiest to use. They usually have a linseed oil binder that allows plenty of time to remove the excess before the stain dries.
You generally don't need to sand new wood that has been stained before painting, but it depends on the results you're after.

Minwax PolyShades combines stain and polyurethane in one simple step.
To remove a stain from wood without sanding, use a mixture of baking soda and water or a wood-specific cleaner. Apply gently with a soft cloth and rub in the direction of the grain. For tougher stains, a bit of white vinegar can help. Avoid abrasive methods to prevent damage.
Lightly sand between coats with 220-grit sandpaper to improve coat-to-coat adhesion and carefully remove all sanding dust before recoating. Failure to follow these steps may result in adhesion problems.

Whenever water or any stain or finish that contains water comes in contact with wood, it causes the wood fibers to swell, which is called “grain raising” or “raised grain.” After the water has dried the wood feels rough to the touch, and thinly applied finishes also feel rough.
The main wood smoothing tools at your disposal are sandpaper, scrapers, planes, rasps and files. Each has its advantages.
By using steel wool to carefully smooth the wood surface, you can take out the rough spots without sanding through the patina. Fine steel wool should also be used on thin veneer. Veneer is a layer of wood glued to another piece of wood. Sometimes it is paper thin.
