grammar - it's important that he... -- it's important for him to

I'm always struggling with these structures:

1) It's important/vital/essential that + subject + (should +) verb

• It's vital that you (should) do exactly as I say.



• It's important that they (should) attend every day.


• It's essential that everyone (should) be here on time.

2) It's strange/natural/interesting/curious that + subject + should + verb

• It's curious that they should offer him the job.


• It's strange that he should be late.


• It's only natural that parents worry about their children.

Even though I know these sentences are grammatically correct I find them a little complicated and cumbersome with all the "shoulds" and subjunctives and everything, so I tend to avoid them and say:

It's important/vital/strange/natural/etc. + for + pronoun + to...

The thing is I'm not sure this is always correct. Do you think it's possible to change the sentences above this way?

• It's vital that you do exactly as I say. → It's vital for you to do exactly as I say.



• It's important that they attend every day. → It's important for them to attend every day.


• It's essential that everyone be here on time. → It's essential for everyone to be here on time.


• It's curious that they should offer him the job. → It's curious for them to offer him the job.


• It's strange that he should be late. → It's strange for him to be late.


• It's only natural that parents worry about their children. → It's only natural for parents to worry about their children.

So can I think of this as a rule that works (at least) most of the time?

Thanks.
