So if I get CPL filter this will help me with better pictures like this?

But which one is better to get? Hoya or Marumi? But there is also more models under every brand. I am newbie but I am lost with all this.
And for rubber lens hood I select same size as filter? My lenses are 77mm or I need to check anything else? Is good enough if I get one from china or is better from specialized manufacturer?
I used to be a Hoya fan until 2 of their CP Filters had issues - one of them broke apart where the frame rotates, and the other most likely will do so if I continue to use it. I switched to
B+W as well as
Formatt Hitech. BUT the ones I linked are slim filters (meaning the depth from the front to the back of the filters is thin). Thicker depth filters can cause vignetting especially when shooting wider. Marumi is a decent brand from what I've read although I've never used one. If you are going to screw on a rubber lens hood to the front of a CP filter, I'm not sure if a slim filter would allow you much room to screw on a hood. The hood might fall off easily since it wouldn't be able to screw on as much as on a regular filter.
For something like your example, a rubber lens hood won't work any better than a regular lens hood. A rubber lens hood is useful if you are going to place the front of your lens against the glass (aquariums are a good example of that use). But if you want to shoot an entire display, putting a lens against the glass won't allow you to capture the entire display. That's when a regular lens hood would work just as well as a rubber one.
If you are standing back to shoot through glass and cut reflections, sometimes a CP filter helps. It depends on the source of the reflections. My church has beautiful etched glass between the Narthex and Sanctuary. But the problem is behind where I stand to photograph it are glass doors to the parking lot. No matter what brand of CP filter I use, I cannot get rid of the car reflections. Most likely I will have to cover the doors with something to eliminate that type of reflection.
Some CP filters make you lose light stops more than others (meaning the glass is darker).
