And even then he had to resort to using Padme as bait and Anakin was forced to take the bait because the Jedi kept the Knights of their Order from learning Force Healing until they became Jedi Masters which is quite selfish of them as the worst case scenario would be the Jedi Knights overexpending themselves.
Since Jedi could heal and resurrect the dead with Force Healing it’s clear that the power to “cheat death” that Sidious spoke of is not Force Healing as the power to “cheat death” has been achieved by one entity not multiple.
Since healing and resurrection aren’t considered cheating death by Sidious what is? He also implies that cheating death requires power. Could he be suggesting an ability that doesn’t require any equivalent exchange of life energies? He did suggest manipulating Midi-Chlorians to create life so said manipulation could bypass the equivalent exchange needed to resurrect the dead thus cheating death.
In any case Sidious only got a grip on Anakin due to offering a potential solution to Padme’s death while the Jedi withheld such solutions(of course Anakin simply told Yoda that he had a vision of someone dying not that said someone was dying of an ailment which could be resolved with Force Healing).
If Anakin knew of Force Healing then Sidious would have ultimately been killed by Mace Windu. Sidious only won because Force Healing wasn’t made known to Jedi Knights only to Jedi Masters.
If Anakin knew of Force Healing then when Sidious told him of Darth Plagueis’s ability to keep others from dying he’d mention Force Healing which would get a rebuttal from Sidious that Plagueis could preform the technique without giving up his or anyone else’s life which would get a rebuttal from Anakin of how that proves that Sith are selfish while Jedi are selfless.
Sifo-Dyas ordered Clones then when Sidious discovered the purchase got offed by the Pykes before coming up with a template then Tyranus sent Jango Fett along with the Microchips to serve as the template.
Who knows who Sifo-Dyas wanted as the template before Sidious had Tyranus kill him. For all we know he was going to give his own DNA for the project! All we know is that the guy paid for a Clone Army but died before acquiring the template as the plan was stolen by the Sith.
