In my personal experience if you have to pick one, animal manure (I count human poop under that as well) works better than compost from just plant material (like plant cuttings, kitchen waste, weeds, wood chip …). Best is a mix of both.
“Night soil” (human poop) fertilizer has a way higher risk of disease to humans than manure (animal poop) because it’s rare for pathogens to infect multiple species. Some pathogens do cross species lines - avoiding nightsoil on human food crops is not a standalone protection - but it’s an important way to significantly reduce risk.
Septic tank discharge fields are great places for flower gardens. No veggies.

And only salt-tolerant flowers at that. Septic field tend to build up in salinity over time due to our diets
But if you fully compost ( with temperature monitoring and like good com.post management) then composting will sterilize the soil.
