You've already upgraded that Mac as far as it can go. You cannot upgrade that iMac to macOS 10.14 (Mojave), let alone upgrade it six major versions to macOS 14 (Sonoma).
Firefox 115 ESR might let you browse some Web sites that are causing problems for High Sierra's version of Safari. But Mozilla is moving on, and will stop providing "critical security updates" for it some time this month.
