Is there a reason why you do not do a $this->getFields(...) and then return the field with Id if it exists?
That would save a lot of (duplicated) code in the new function?

so something like this:

public static function getField(
        $context,
        $fieldId,
        $item = null,
        $prepareValue = false,
        ?object $valueToOverride = null,
        bool $includeSubformFields = false
    ) {
        $fields = $this->getFields($context, $item, $prepareValue, $valuesToOverride, $includeSubformFields);
        $fields = array_column($fields, NULL, 'id');
        return $fields[$fieldId] ?? null;
}
