Rebounding with Hinge (or something else)

I (40M) am very recently separated from my partner of 16 years. It's more or less amicable (although nothing is perfect of course). My ex has already been on a few dates, and she really thinks that I should try dating to see what life is like out there.

Personally, I feel like I need a while to decompress and be alone. I've been in consecutive long-term relationships since my early 20s, On the other hand, I feel really bad about the unraveling of this relationship that both of us expected to last the rest of our lives, and so maybe getting to know some new people might do me good in this transitional time.

I heard mostly good things about Hinge, although I've never online dated. Additionally, I really do not want to get into anything serious, and so it almost feels unethical to go on dates with people when I don't have any long-term objectives. Is that mostly what Hinge users are seeking? Is there maybe something better I should be doing?

I'm not even sure if this is the right place to ask this, but this community seems pretty positive, so I'm open to hearing any and all advice. If it isn't appropriate to have asked here, my sincere apologies. And as I said, I definitely do not want to just dive in and, consequently, waste someone's time or hurt them. Thank you!
