I like your existing railing too. It’s appropriate for your house and it’s attractive. I’m not sure about painting it a different color or wood tone so it “pops.” I don’t think I’d like a popping railing. Use a contrasting color or wood tone for a handsome front door. A popping door would be ok.

"Per the ICC, a guardrail is a must when the distance from the grade below to the walking surface above is greater than 30 inches."

Just throwing out some considerations. I’m having a hard time imagining glass on these steps; what is the plan with the small gap to pillars. Your inspiration picture has a natural end on the stairs and I think you would have to extend yours. I also think the look below would be more complementary to your home’s style. I wouldn’t be selecting based on your rationale: It won’t start a new trend, not doing won’t date the house and it will remain the same overall. If you love the idea, that’s a different thing. The back stairs can be different.

It looks like your house color is similar to ours. We used white for railings etc. but black for house and garage doors (see picture below taken last fall...) The porch floor is a gray color. We chose our colors based on the colors used on a historical house in the old part of our town. It was simple and goes well with most other things. I think it would work well for your place.
