Well, for me, a unit isn’t always equal to a class. In other words: I test several classes together. I know people have strong opinions about isolation- for me, it works just fine, and there are several TDD practioners who advocate this style (among them Martin Fowler and Kent Beck, if I‘m not mistaken).
That's a fair approach. I'm certainly not dogmatic about this stuff; as long as you have a good understanding of the pros and cons involved and accept them, like you do here, that's fine. I do think this takes a bit more discipline around understanding what the "unit under test" is, so adoption could be an issue depending your team.
I don't recall reading anything by Fowler on this specific subject and I ❤️ that man. You wouldn't happen to know the book/blog/talk off hand would you? Sometimes searching for these things can prove to be difficult.
I found a pretty lengthy explanation of Robert Martin, a.k.a. Uncle Bob, who also prefers to test several classes at once if necessary: blog.cleancoder.com/uncle-bob/2017...

You get fewer tests, that don’t break easily when the implementation changes. The downside is errors are a bit more difficult to find.
