For material design, their guidelines recommend no periods on one sentence of UI text.
I don't have access to research verifying the material guidelines, but here is their viewpoint on making text concise and readable:
From Material Design writing
Salesforce's lightning design system:
Omit the period after items in a bulleted or other type of list only if the items are fragments rather than complete sentences. However, a period is necessary at the end of a sentence whenever more than one sentence exists for that bullet. In this case, make all bullets complete sentences that end in periods so that each bullet is parallel.
Again, I don't have cited research links, but these are organizations that have put in research into a large amount of design decisions.
