Techniques for handling opening a new tab and ensuring web accessibility with WCAG 3.2

WCAG 3.2 indicates that content should be provided in a predictable format and that subsequently when a new tab is opened on a click that the user is made aware of this.

I have a webpage with a list of many links that open in a new tab. W3C recommends that either this is indicated in the link text or an indicator is provided on hover/focus. However, because of the extensive amount of links on the same page that require this, providing these options would significantly disrupt the design/UI.

Are there are other less visually intrusive ways to achieve this conformance without providing a pop-up or text warning for each link?

Also, are there other accessibility issues related to opening new windows/tabs?
