Did u perform all 4 steps from my scenarion with 2 parallel transactions? If i didn't have enough permissions then i guess I would not get right result when execute sql query from the second transaction separately.

On my environment it working fine, see below:
postgres=# WITH
cte1 AS (
SELECT t2c2 FROM t2 WHERE t2c1 = 'string_value_2'
),
cte2 AS (
SELECT * FROM t1
WHERE
t1c1 = 123456789
AND t1c2 = (SELECT t2c2 FROM cte1)
FOR UPDATE
)
SELECT * FROM cte2;
_pk | t1c1 | t1c2 | t1c3
-----+-----------+------+----------------
1 | 123456789 | 100 | string_value_1
(1 row)
Are you sure, user executing these SQLs have appropriate permissions on respective table? Is there any error or warnings (check server log too)?

insert into t1 (t1c1, t1c2, t1c3) values(123456789, 100, 'string_value_1');
insert into t2 (t2c1, t2c2) values('string_value_2', 100);

What is output of following queries:
1. SELECT t2c2 FROM t2 WHERE t2c1 = "string_value_2" 2. SELECT * FROM t1 WHERE t1c1 = 123456789 AND t1c2 IN (SELECT t2c2 FROM t2 WHERE t2c1 = "string_value_2")
