In that case, which type of visa would I need?
You will need a C Short-Stay uniform visa, that allows you to stay for 90 days in a 180-day period during your visa validity
at which consular authority?
It depends where you want to go in Schengen
The Schengen visa code states :
The Member State competent for examining and deciding on an application for a uniform visa shall be:
(a)
the Member State whose territory constitutes the sole destination of the visit(s);
(b)
if the visit includes more than one destination, the Member State whose territory constitutes the main destination of the visit(s) in terms of the length or purpose of stay; or
(c)
if no main destination can be determined, the Member State whose external border the applicant intends to cross in order to enter the territory of the Member States.
A main destination can be taken as the longest stay or if you have your main reason to visit the Schengen area there (a meeting, familiy event...)
