Welcome to the forum (in case you are new – I don’t remember your particular sign-in) — but here is my unofficial welcome in any case.
I’ll volunteer a first answer here as a long-time commenter and lurker in these here parts (does that make me a member?).
I think it could safely be said to be a consensus among evolutionary creationists here that the flood referred to in Genesis was not global in the modern understanding of that word --meaning covering the whole planet. As to whether a flood happened or not, I think most here put forward that the story is probably centered around a real flood event, but that the details wouldn’t at all look like what we would imagine if we were to pretend that the Genesis narratives were no more than a kind of news story trying to set out historical facts like a modern newspaper may try to do.
I suspect you would/will get a range of answers on how much historical correspondence to expect from details. But probably most (unless they are YEC --and yes, they are welcome and present here too!) would not accept that there was a planet-wide flood that does everything that YECs require of it.
Others can weigh in as well … there will probably be greater variation on how much of the Exodus events should be read as straight numerical claims. I think what many here will agree on, though, is that concerns over numerical/chronological accuracy as prerequisite gatekeepers for taking any ancient text seriously is almost certainly a misapplied modern concern that does violence to the narratives. That’s my two-cents, anyway.
Of course nobody here speaks for all Biologos “membership”, whatever that is, or if somebody does it should probably be a moderator who at least has some official status. But hopefully you’ll get a variety of responses.
