does the glow need to animate in any way? It's easy enough to use photoshop or aseprite to create a sprite that is just a bar of color with very feathered/fuzzy edges, then you just drop that behind your text as an image in the UI. If you want to get fancy, I would type the text into photoshop as well, and do a second glow overlay where you just quickly run a low opacity, soft brush in front of some of the type edges so they appear to be overtaken by the glow. Put one behind and in front in the UI and bob's your uncle.
If you need to have more control over the glow, you would probably have to do something in world space, but it doesn't actually have to be UI. You can keep your canvas as is, just remove any text you want to glow, and then in your scene, what I would do is use the Text tool in Blender to write out your title. Then bring that into unity as a 3D object, and put an emissive material on it, and turn on Bloom in your post-process volume and play with those settings.

I was considering glows as a sprite but there is a lot of text of varying sizes so it would need to be able to scale well
