What to do after courthouse wedding?

Due to Covid our original venue has not been able to reopen so we moved the reception date to October and having the wedding ceremony on our original date but outside on the lawn of our cities courthouse. We cut the guest list of the ceremony from 74 people to just the wedding party of 8. Here is the problem, do we do anything after the ceremony with our guests? Feels odd to spend the whole day getting ready for something only to see our guests for two hours tops when including first look and pictures. I suggested we maybe do dinner after as we should be done around 5-5:30 but I have a bridesmaid who has Crones so she is not comfortable going to a restaurant to eat and my FH is also not comfortable with the idea. Both are fine with going to a restaurant and picking up something to go and eating somewhere as a group that is not a public space with everyone sitting at a distance. Using someone's backyard is not an option as no one has a large enough yard for everyone to space out enough. I want everyone to feel safe and comfortable as they are putting themselves at risk coming to be witnesses. Any suggestions?
