I understand why it would be a concern if that's what you had been expecting.
A lot of places didn't have open evenings pre-COVID, particularly at primary, so local reputation, walk-bys, comparison reports as linked earlier in the thread, and so on.
I would have loved virtual tours a couple of years ago, DD1 did a mid-year transfer in Y7 the only tour we got was about five minutes of seeing halls and the canteen - we obviously couldn't go into any room with kids in it - and we could only talk to the receptionist and deputy head (which could have been done by phone). My DS1 chose a KS4 college programme at 14 and tours were prospective students only, wrapped in as part of the taster day, so I could only go by what he said, the contact KS4 staff member, and facebook discussions with parents whose kids were in that and similar programmes (as colleges with KS4 programmes aren't included in data for KS4 alongside secondary schools so I could compare A-level results and similar with secondary schools with sixth forums, but not GCSEs or Progress 8).
Even with a full open evening, there can be limits. My DD2 went in Y7 this year, and her open evening was in part of the building this year's Y7s aren't using, in a temporary building so we can only see the 'final facilitise' in CGI, and it was too loud to actually talk to any staff members. I got far more information from the website and emailing.
I home educate for at least primary. I think it can be an excellent choice, but it has its share of risks as well just as any school no matter how it's chosen. As difficult and postcode lottery it is to get SEN help in schools, it's even harder to get any sort of diagnosis or support without it - we're often just left on our own even when it's flagged as an issue by a HCP, home education groups are like trying to herd cats - stability at home is greatly achieved, but not in an home ed social setting - and very very few of them are running right now so isolation is an even bigger concern than usual though if your DD can continue on at the childminder that can be eased, and as others said, the costs and challenges are all on a home educator's shoulders.
Home educating can be lovely, I wouldn't change it most days. Having done both the home ed and the school-at-home-lockdown version, they're overlapping but still very different kettles of fish and right now, my 8-year-old struggles some days as he's essentially in the same lockdown his siblings were in back in June. We can out, but nothing he was doing before March has reopened. It's hard on him and a lot of other home educated kids I know right now.
If the reason to home educate is because reading about schools in COVID is depressing, well, some of the stuff coming out of home education communities right now isn't really that much better. It's a hard time for everyone. A reception age child who can continue on as they are may get some benefits, but every option has some risks.
