If you don't know how to add resource packs to Bedrock Edition, refer to this link: (click here).
To get the resource pack files from the PMC download, right click the downloaded ZIP file and select "Extract all". The resource packs will be in the extracted folder, and you can put them in your Minecraft resource packs folder.

There are many vanilla-styled netherite textures with added accessories, but none of them personally appealed enough to me. I decided to make my own version, adding gold lining and decoration to tools and armor. I also changed the basic shapes of the tools to set them apart from the lower tiers in the game, while still looking relatively "vanilla".

I tried to make the gold blend in nicely with the netherite. I'm not quite sure how I feel about the results now, but I think they're decent.

There are also downloads for a diamond version as requested, which was edited by FmWild57 (thank you for providing the edit).
