Welcome. Please don't expect your strawberries to ripen any more as you wait. They won't, once they are picked from the plant. Waiting will not result in any more sugar content or ripeness. What they actually do is begin to decay, which makes them appear riper but for winemaking nets no real benefits.
What you can do with them is freeze them solid and then get ready to thaw them and make your wine. Freezing will break down the cell walls and make the flavors extract better. That's true of all fruits.
If you have a strawberry grower nearby, now's the time to get their attention and tell them you want all their over-ripes and discards. These are the berries too ripe to be packed and transported for sale. Unless the grower has a flash freezer, they are typically discarded or sold to vintners. I have an order in for 100 pounds this summer. The later in the season you get your berries, the more sugar they will have in them. The berries actually get smaller but have higher sugar content as the season progresses.
Oh BTW, the flash freezer is why bagged frozen strawberries are better for wine than fresh store-bought. Same with blueberries. They are far riper when flash frozen by the producer than the "fresh" ones offered in the produce department that had to travel there.
Anyway, this is what I have learned from the growers here and some experience over time.
