DATETIME(2) is good for you. Data will be stored as "2022-05-18 09:05:03.10".

Precision can be raised to DATETIME(6) (µsec).

You will be able to get events +/− 0.5 seconds with :

SELECT ALL ...
FROM ...
WHERE event_at
    BETWEEN '2022-05-18 09:05:03.10' - INTERVAL 0.5 SECOND
    AND '2022-05-18 09:05:03.10' + INTERVAL 0.5 SECOND

MICROSECOND interval can be used too https://dev.mysql.com/doc/refman/8.0/en/expressions.html#temporal-intervals
