What about Nexperia’s (formerly NXP) dual transistors:
https://www.nexperia.com/products/bipolar-transistors/general-purpose-bipolar-transistors/matched-pair-transistors/#/p=1,s=0,f=,c=,rpp=,fs=0,sc=,so=,es=

Diodes Inc also makes some:

Not on the same chip, but matched and two transistors in one package. Can they be used in an expo converter?
