Seattle has a very over-complicated overhead system so the trams can share streets with electric trolly buses. It took took a lot of additional time to deploy due to that. Wellington decided to ditch electric trolly buses (and ignored recommendations by residents to re-implement an airport/golden-mile tram, sadly).
The battery tech in non-overheard wire based trams is still pretty expensive and high maintenance. I really don't think it's worth the price.
Rail take years to setup, and despite it being amazing and necessary, it's also political suicide in America's "We hate public transport because <insert reason here>" America is decades behinds the world in real public transport; including mid/high income countries that are way less densely populated.
