context generally has really goid guides that can be hired privately as well.. or just take a half day introductory tour for orientation and plan the rest yourself. I realky lijje to do the planning myself but a mix of wandering down streets yourself and gaining knowledge on a subject or historical period you ate interested in is a good mix. A guide might be able to get into places before regular opening hours., there is probably a lot that has changed in the past year and a local guide could be a good investment.
