If all links on my site open in new tabs, will it affect analytics or SEO?

I’m working on a site where all links in the body of the pages open to a new tab. Generally I see external links open to a new tab but internal in the same tab. Wondering if this can still fall within a best practice.

Seems like it shouldn’t affect Analytics (new session), but wondering if there are SEO ramifications. Do you see higher bounce rates on sites that do this? If someone is opening multiple tabs, does looking at a user’s path through your site become muddied?

Could use some feedback on the pros/cons. Thanks!
