I didn't read much of the previous threads, but seem to have dipped into this one at the right moment.
I'm currently transcribing C18th & C19th wills of rich Edinburghers (including women, who owned moveable wealth and also could and did own and bequeath property, although not to the same extent as men) and reading newspapers of 1760–1820.
Based on that, I can say that without a shadow of a doubt the working class poor of Edinburgh, male and female, benefitted from slavery and colonial wealth generally.
The city's institutions included the Infirmary, the Dispensary, the Orphan Hospital and of course the churches which provided schools and alms (the Kirk Sessions frequently paid for childbirth expenses, for example, before trying to recoup these from recalcitrant fathers).
These institutions were funded to some extent by taxes on the city's wealthy or traders and were also the frequent beneficiaries of legacies in the wills, and of collections subscribed to by the great and good of the city (and indeed by many of the less elevated folk, eg "soldiers of the 73rd Regt" or "staff at the Customs House".) There were also frequent subscriptions taken up for specific causes, eg "for the relief of operative weavers" or "for the widow and children of the stonemason killed during the late collapse of the building in Wotsit Wynd". The situation will doubtless have been the same in other Scottish cities.
The money given to these collections and taken in taxes originated from, amongst others, families who traded to India, Trinidad, Jamaica, Australia, South Africa, China... They often had a branch of the family settled there for convenience. The documents I've read in the last couple of weeks alone have members of families spread from Demerara to New Zealand.
Beyond the merchant families and slave-owners, Empire wealth was dispersed in Scotland through routes such as employment provided in processing and selling the goods acquired through Empire: cotton, sugar, tobacco, indigo spring to mind. All four of those crops used either slave labour or (IIRC in the case of indigo) coerced labour. The Empire also provided a market for the finished goods: a lot of Dundee jute products, for example, went to the Americas and Caribbean. IIRC, Dundee even wove a specific type of cloth used primarily for clothing for enslaved people. Both handloom weaving, and powerloom weaving in factories, were jobs done by both women and men.
The Empire also provided direct employment for the less well-heeled: sailors and those servicing the Royal Navy, Hon East India Company and merchant navy generally. The army posted a huge number of working class soldiers around the world, some of whom settled and invited other family members out or once again used the "foot in each country" as a business opportunity. Then many went out to the colonies just as very small traders, artisans or settlers, and went as whole families. There were many, many active schemes for settlement. The "ten pound Poms" of the C20th was just a recent incarnation of what had been going on for over a century. Women were very much part of these settlements.
Women may have typically had less agency than men, but I absolutely wouldn't describe them as uniformly without agency. One can't spend any time reading women's wills, letters or newspaper items about them without their agency becoming obvious.
