That circuit is the standard instrumentation amplifier circuit, your search term is "instrumentation amplifier".
These days you don't need build a discrete amp like that, it all comes inside a single chip with one external
resistor to set the gain. For instance INA333 data sheet, product information and support | TI.com
(Incidentally opamp circuits typically only use the resistor ratios, so the absolute
value of the resistors is chosen to optimize noise v. power consumption, and is
in the typical range of 1k to 50k)
