The license options and details on the SRX are outlined here.
https://www.juniper.net/documentation/us/en/software/license/juniper-licensing-user-guide/topics/concept/licenses-for-srx.html
Logical systems are only supported on the 4 digit models that you are looking at. And no longer require a license for use as noted in the above document.
---------
Starting in Junos OS Releases 20.3R3, 20.4R2, 21.1R2, and 21.2R1, you can use the features for logical systems and tenant systems without a license.
Starting in Junos OS Release 18.3R1, an SRX Series Firewall running logical systems or tenant systems includes three licenses by default. One license for a primary logical system and the other two licenses for user-defined logical system or tenant system. The system does not allow you to configure additional logical systems or tenant systems if the number of logical systems and tenant systems exceeds the number of available licenses. In the earlier releases, the system allowed you to configure an additional logical system even if the number of logical systems exceeds the number of available licenses, but with a warning message of non-licensed logical-systems do not pass traffic. You can purchase licenses for additional logical systems and tenant systems that you intend to create. If you intend to configure an interconnect logical system or interconnect tenant system to use as a switch, it also requires separate licenses.

Subject: Logical System, licenses and scaling numbers?
Hi,
Do you need a license to enable Logical System and/or Tenants on the new SRX1600, SRX2300 etc? How many logical systems are supported on each SRX plattform?
Thanks
Anders
