Contract Stipulations to Avoid Liability Litigation

I work for a Wordpress development agency, and I’ve recently been tasked by our team’s director to brainstorm potential areas of concern in terms of possible liability issues related to future contracts. The management and senior staff are all very old school and have been working since practically the dawn of Wordpress, and they are admittedly pretty out of touch with current industry standards. They do a lot of business, and have avoided any legal issues so far, but the possibility of partnering with a few new marketing firms has got them anxious.

They have asked us to think of areas that they could address in future contracts to avoid litigation due to liability (such as our hosting provider going down, possible data breaches, ADA compliance, etc.) They have made it very clear that they are not expecting us to write contracts or be legal experts, and that everything we bring forth will just be in addition to the legal guidance they will be receiving. I was just curious if anyone out there had some guidance on what we can and cannot include in future contracts to protect ourselves.
