Open EMR was the first choice for our project, but it did fit our workflow needs and the UI/UX is also quite outdated. It's FHIR api also had minimal support. So we ended up building our own EMR on top of HAPI FHIR repository, (https://hapifhir.io).

the latest version of openemr is supporting FHIR resources very well. The API is well documented too.https://github.com/openemr/openemr/blob/master/API_README.md

There is definitely support, but it is nowhere near what is documented in FHIR website. You can look at the search capabilities for example : https://www.hl7.org/fhir/search.html.
