Sourcing good beans and grinding makes the most significance difference in coffee taste. For me, different brewing methodologies is like toasted bread versus untoasted bread. One isn't necessarily better than the other ... it's more a matter of one's taste at the time.
For basic coffee flavor ... the simple French Press consistency does one hell of a job.
As to self-roasting ... for most people it is probably more effort than the return you get in taste. It does provide maximum Quality Control and flexibility in beans, roasting time and temps. Some people will alter temps across the course of roasting and will gather roasting temps/times/batch size/airflow/rotation rate/et al and produce graphs and stuff.
This is an example of a simple graph: "
This graph shows 12 batches, all 500 grams, roasted by Steffen. They were not that different in power and fan setting during the roast.
X-axis is the TP temperature and Y-axis is the time for FC start.
This plot shows the tendency of a higher TP temp to give a shorter time to FC start.

When I first started getting into coffee, I did a lot of reading. As one would expect, similar to wine, the soil/clime makes a difference in taste(s). Coffee beans harvested from the red soils of Ethiopia, (where coffee beans were first discovered to have a kick), have a different taste than coffee beans harvested from rain swept soils of Central America. That sorta started my journey with coffee ... going around the world trying different coffees.
While I have and continue to source coffee from different internet purveyors ... my goto place is Sweet Maria's in Oakland, California. (In a pinch there are a few coffee roasters in the general neighbor which are happy to sell me unroasted beans. They were surprised by my request and wanted to sample my roast.)
