My troop is 80+ years old, however I just took over a few months ago. The troop was doing very poorly when I took over: only 7 registered youth, rarely camping, no summer camp in several years, previous Scoutmaster didn't even want to be the Scoutmaster, no Patrol spirit/identity, both the adults and youth had no idea how the program was supposed to work (no Patrol Method, no training, etc).
This was a troop that had a strong program and 30+ youth 15 years ago, chartered by a large-ish church.
I don't think the troop produced any paper-Eagles in those 15 years (I kept in touch), but when I took over, the head of the church asked for better Eagle Projects.
As for girls, I'm fine with that. Character-building isn't only for boys. There is Girl Scouts of the USA (GSA) troops that have good outdoor programs but they are very few and far in-between. They are more known for "glamping" and selling cookies. Gold Award doesn't have the same recognition as Eagle Scout. Something that I found out: GSA troops are not always sponsered by an organization, and those that are sponsered, are not owned by the sponsering organization. In contrast, all BSA troops have a sponsering(chartering) organization and the sponser owns the troop. So, GSA and BSA have different programs and fulfil different needs. It's good that more youth now have more options for personal growth.
If I had a daughter and BSA wasn't available, I would look into American Heritage Girls (a scout-like organization, sometimes called Heritage Scouts) or another program like that. The BSA has had co-ed programs for 14-21 year olds since the 1970s though: Venturing, Varsity, and Explorers. However I think it's just Venturing now, IDK.
FYI, in Cub Scouts, boys and girls are seperated by dens (patrols). In Scouts BSA (renamed from Boy Scouts where youth can earn Eagle), boys and girls are seperated by troops (but can have same number, same chartering org, etc... just separate youth structure).
