MicrosoftHi Berkowitz_Admin,
Block download option for specific people links: This should be available today for Office fielse.
Block downloads option with edit access: This is not available as a link option but I would definitely check out some of the conditional access policies here to see if they may help.
Block Download option for non-Office files: Stay tuned 🙂 We're working on this and should have more to share very soon!
Expiration on link types other than Anyone: We are working on an expiring external access feature which scratches many of the same itches as what you are describing (plus a few others). Check out our SharePoint Conference talk from earlier this year for a peek & a demo.
Hope that helps!
