Displaying Lists (in web parts) between site collections/group team sites

Try the Highlighted content web part on Modern Team sites or groups - https://support.office.com/en-us/article/use-the-highlighted-content-web-part-e34199b0-ff1a-47fb-8f4d-dbcaed329efd. This could query a library or list in the current site collection or a Managed metadata mapped field from any other Site Collection.

If you have a developer route, then can use SPFx list view control - https://sharepoint.github.io/sp-dev-fx-controls-react/controls/ListView/. We recently used it to build a similar functionality and works really great will all list view functionalities. On an effort level, took us about roughly 2-3 days to implement and test.
