To give a concrete example of a job* where you're doing all the things all the time (at least in my experience) is office manager at a start up company. It doesn't sound glorious, but it's super varied!
I currently do, among things I'll forget to mention :
invoicing and payments
basic accounting
hr
day to day office running (making sure we have supplies, watering the plants, organising lunch, answering operational questions)
set up and maintain the company knowledge database and teach people how to use it
same for client database
event planning (fairs, team building, company parties)
organise courses and learnings
research
agenda keeping for the CEO
man the phone
random things that you can't really pin down like remind people to clean their desk (we don't have a cleaning service), run to the supermarket because it's hot and the boss is buying us ice cream, give info to new employees moving to the country on where to buy the best coffee)
It's never boring and also not stressful (for me, I thrive on organising thing).
*I don't know if this is a career. Personally I just want to go to work, work, go home and get paid to have money to do the things I like. I don't need fancy new title or promotions that come with more responsibilities and stress.
