Wall tiles - edge finishing

Hello forum, I would like to tile a wall in the hallway halfway up. I have small tiles measuring 10x10. I have never tiled before and therefore have no experience. Nevertheless, I would like to give it a try. How do I finish the top edge of the tiled wall? It will be at about 120cm height. Do I use a trim strip like the ones I see everywhere in the bathroom? Doesn't that then make it look like a "bathroom" in the hallway? Does anyone have a good idea for the top edge finish?

Just google Schlüterwinkelprofile. There is everything. Black, white, silver, chrome. Glossy, matte, brushed. Round, flat, angular. You can choose the most beautiful one for your taste.

Or simply a suitable tile border

A border tile is a tile, I thought? How do you then finish it off at the top, basically on the edge you see when looking at it from above? On the edge of the tile, basically the one that sticks to the wall with the adhesive.

The border is the finish. There are also rounded finishes. And, if you think it doesn't look quite clean, then acrylic joint as a connection to the rest of the wall, as it can be painted over.

Some also simply paint directly over the tile edge. It depends on how the edge ultimately forms.
